What does the pentagon represent?
The Pentagon is the headquarters building of the United States Department of Defense. As a symbol of the U.S. military, the phrase The Pentagon is also often used as a metonym or synecdoche for the Department of Defense and its leadership.
Considering that fact, why does the Pentagon have 5 sides?Why is the Pentagon, you know, a pentagon? The land the Pentagon was first planned to go on was bordered on five sides by roads, so the architects designed a five-sided building. Builders broke ground for the Pentagon on Sept. 11, 1941, exactly 60 years before the Sept.
Аdditionally what is the significance of the shape of the Pentagon?The building was originally designed to fit onto a tract of land with borders on five sides. In the end, it was built elsewhere, at a site where a pentagonal shape was no longer essential. But by the time of this location change, it was too late to come up with a new design. So it remained a pentagon.
Accordingly, we may wonder what is shape of pentagon?In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting.

If we are talking about a two dimensional shape, there is equilateral pentagon. Length of each line is equal to the other ones and the angle between two lines is 108°, which makes up to a sum of inner angles 540°. In this situation there will be no parallel lines and it has 5 sides.

All pentagons have five straight sides, but the sides do not have to be of equal length. A regular pentagon has five equal sides and five equal angles.
A regular pentagon must have five congruent sides, five congruent interior angles, and congruent exterior angles: five congruent sides (sides of equal length) five congruent interior angles (each measuring 108° ) five congruent exterior angles of 72°
Diamond. The diamond shaped face is the rarest of face shapes, and is defined by a narrow forehead, wide cheekbones and a narrow chin. Diamond shaped faces are usually narrower at the eye line and jaw line, with high and often dramatic cheekbones.
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended.
A quadrilateral can have four right angles. Sum of Interior Angles = 540'. Four right angles would leave 180', which is impossible. So a pentagon has a maximum of three right angles, as shown.

Sum of Interior Angles = 540'. Four right angles would leave 180', which is impossible. So a pentagon has a maximum of three right angles, as shown. 6 right angles = 540', leaving 360', which is impossible.
Find An Angle In A Pentagon : Example Question #3 There are 5 interior angles in a pentagon. Divide the total possible angle by 5 to determine the value of one interior angle. Each interior angle of a pentagon is 108 degrees.
Pentagons are geometric objects with five straight sides. The prefix “penta” comes from the Greek word for “five.” A regular pentagon has five equal sides. To find the area of a regular pentagon, divide the pentagon into five equal triangles.
Now the measure of each central angle is equal to 360/5 = 72 degrees. So, the measure of the central angle of a regular pentagon is equal to 72 degrees.Angles in a Pentagon.
|Measure of each of the Angle (in a Regular Polygon) =||180 degrees ×(n−2) / n, where n is the number of sides/.|
A regular pentagon has no right angles ( It has interior angles each equal to 108 degrees). An irregular pentagon has at most three right angles, because a fourth would leave 180 degrees to be used for the final angle that is (540 degrees - 360 degrees), which is a straight line.
