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.
Does a pentagon have 5 or 6 sides?
A regular pentagon has all equal sides and angles. In a regular pentagon, its interior angles are 108 degrees and its exterior angles are 72 degrees. The angles of a pentagon add up to 540 degrees. In an irregular pentagon, pentagon sides and angles can be different sizes.
What’s a pentagon look like?
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.
How many sides has a octagon?
8Octagon / Number of edges In simple words, the octagon is an 8-sided polygon, also called 8-gon, in a two-dimensional plane. A regular octagon will have all its sides equal in length. Each interior angle of a regular octagon is equal to 135°. Therefore, the measure of exterior angle becomes 180° – 135° = 45°.
