What is a pentagon in math?
A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting.
What is a 5-sided shape called pentagon?
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning 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. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.

Is a pentagon 5 triangles?
The pentagon is divided into five identical isosceles triangles. Each triangle has one angle that is 360° ÷ 5 = 72° and two equal angles (�� in the diagram).
What are examples of pentagon?

How many pentagons are there in the following figure?
Hence, there are 28 pentagons in the given figure.
What objects look like pentagons?
Diamond. If you look at the two-dimensional projection of a diamond on a piece of paper, you can observe that its outer boundary consists of five sides and five corners. Hence, a diamond is clearly an example of pentagon-shaped objects in real life.
Do pentagons have right angles?
So a pentagon has a maximum of three right angles, as shown. Sum of Angles = 720′. 5 right angles = 450′, leaving 270′.
How many angles does a pentagon have?
5
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.
How many triangles are in a pentagon?
35 triangles
There are 35 triangles that can be found inside a regular pentagon.
