# For any two similar figures, which transformation can you use to make them congruent to each other??

So two figures are congruent if you can map them onto each other using a series of rigid transformations so that corresponding parts are equal to each other, and two figures are similar if you can map them onto each other using rigid transformations and a dilation.

## Bearing in mind, which transformations will create congruent figures?

Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

## Considering that fact, which transformation will create a similar and a congruent triangle?

The correct answer is: dilation and rotation.

## In view of this, can two figures be similar congruent?

Two figures are congruent if they have the same shape and size. Two angles are congruent if they have the same measure. Two figures are similar if they have the same shape but not necessarily the same size. All of the figures below are congruent since they all have the same shape and size.

#### When two triangles are congruent we get how many Congruences?

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

#### Can SSA prove triangles congruent?

The SSA (or ASS) combination deals with two sides and the non-included angle. This combination is humorously referred to as the "Donkey Theorem". SSA (or ASS) is NOT a universal method to prove triangles congruent since it cannot guarantee that the shapes of the triangles formed will always be the same.

#### Is SAA a valid means for establishing triangle congruence?

Answer: SAA is not a valid means for establishing congruence.

#### Is SAA a congruence theorem?

AAS Congruence. Angle-Angle-Side (AAS or SAA) Congruence Theorem: If two angles and a non-included side in one triangle are congruent to two corresponding angles and a non-included side in another triangle, then the triangles are congruent.

#### How do you prove triangles are congruent?

Side-Side-Side is a rule used to prove whether a given set of triangles are congruent. The SSS rule states that: If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

#### Are any two squares always similar?

Now, all squares are always similar. Their size may not be equal but their ratios of corresponding parts will always be equal. As, the ratio of their corresponding sides is equal hence, the two squares are similar.

#### Is SAA valid?

SAA is valid even in "neutral/absolute geometry", which takes no stand on the Parallel Postulate—or, equivalently, the Angle-Sum Theorem. (Importantly, Side-Angle-Side itself is a postulate in neutral geometry, because you have to start somewhere when comparing triangles.)

#### Does congruent mean equal?

Congruent or Congruence
Definition: congruent means that objects have the same shape. It does not mean that they are 'equal', exactly. People often confuse this word with 'equal,' but there is a small difference in the way that these two words should be used.

#### How do you know if 2 figures are similar but not congruent?

We can also say that their side lengths are the same and that their angle measures are the same. Sometimes, two figures will be similar. Similar means that the figures have the same shape, but not the same size. Similar figures are not congruent.

#### Which airlines are still flying to South Africa?

Qatar Airways, Singapore Airlines, Lufthansa, Swiss International Airlines, Air France, Egyptair, Ethiopian Airlines, Kenya Airways and Rwandair continue to operate flights to and from South Africa, enabling South Africans to reach various destinations in their flight networks.

#### Which pairs of figures are congruent which pairs are similar?

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

#### What is SSS AAS SAS ASA?

SSS stands for “side, side, side” and means that we have two triangles with all three sides equal. If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent. SAS (side, angle, side)

#### What is ASA SSS SAS?

SSS (side-side-side) All three corresponding sides are congruent. SAS (side-angle-side) Two sides and the angle between them are congruent. ASA (angle-side-angle)

#### How do you know if SSS triangles are similar?

SSS. SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio. If two triangles have three pairs of sides in the same ratio, then the triangles are similar.

#### What are the 5 triangle congruence theorems?

There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.
• SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal.
• SAS (side, angle, side)
• ASA (angle, side, angle)
• AAS (angle, angle, side)
• HL (hypotenuse, leg)

#### How can you tell if two quadrilaterals are similar?

You can identify similar polygons by comparing their corresponding angles and sides. As you see in the following figure, quadrilateral WXYZ is the same shape as quadrilateral ABCD, but it's ten times larger (though not drawn to scale, of course). These quadrilaterals are therefore similar.

#### Do similar triangles have the same angles?

Similar triangles have the same corresponding angle measures and proportional side lengths.

#### How do you know if two figures are similar?

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal.

#### What are the 3 triangle similarity theorems?

These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS), are foolproof methods for determining similarity in triangles.

#### Can triangles be congruent by AAA?

Four shortcuts allow students to know two triangles must be congruent: SSS, SAS, ASA, and AAS. Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles.

#### What is ASA congruence rule?

If any two angles and side included between the angles of one triangle are equivalent to the corresponding two angles and side included between the angles of the second triangle, then the two triangles are said to be congruent by ASA rule.

#### Is AAS and ASA the same?

ASA stands for “Angle, Side, Angle”, while AAS means “Angle, Angle, Side”. Two figures are congruent if they are of the same shape and size. ASA refers to any two angles and the included side, whereas AAS refers to the two corresponding angles and the non-included side.

#### How can you tell if two rectangles are similar?

For two rectangles to be similar, their sides have to be proportional (form equal ratios). The ratio of the two longer sides should equal the ratio of the two shorter sides.

#### Is South African Airways still in business?

South Africa's state-owned airline has suspended all its operations as it struggles to raise a bailout of more than 10 billion rands (\$591 million). The business rescue team assigned to manage the company has announced it has failed to raise the money needed to implement a rescue plan for the airline.

#### How do you know if two parallelograms are similar?

Find a pair of possible adjacent side lengths for a similar parallelogram. Explanation: Since the two parallelogram are similar, each of the corresponding sides must have the same ratio. Applying this ratio we are able to find the lengths of a similar parallelogram.

#### What are similar and congruent triangles?

Congruent means that a triangle has the same angle measures and side lengths of another, but it might be positioned differently, maybe rotated. Similar only means the angles are the same. If you have two triangles that have the same angle measures then they will be similar, the sides will be "scaled" versions of them.

#### What does it mean if two polygons are similar?

Two polygons with the same shape are called similar polygons. When two polygons are similar, these two facts both must be true: Corresponding angles are equal.
