Question: What Is Pentagon In Math?

How do you describe a pentagon?

In geometry, a pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to 540°. A pentagon shape is a plane figure, or flat (two-dimensional) 5-sided geometric shape.

What are pentagon shapes?

A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle. The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees.

How do a Pentagon look?

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. If the five sides of a shape are NOT connected or the shape has a curved side(s), it is NOT a pentagon.

What is 5 sided shape called?

A five – sided shape is called a pentagon. A six- sided shape is a hexagon, a seven- sided shape a heptagon, while an octagon has eight sides … The names of polygons are derived from the prefixes of ancient Greek numbers.
