Question

The internal angle of regular pentagon is ___ degree

Answer 1

360 degree is the correct answer

Answer 2

Concept

Pentagon is a 2 dimensional figure having five sides and five angles. In the word "pentagon", penta means five and gon means angle. Types of polygon: convex polygon, equilateral polygon, isogonal figure, etc. Regular pentagon are those pentagons which have equal sides and equal angles.

Given

The internal angle of regular pentagon is ______ degree.

To find

The magnitude of the internal angle.

Explanation

We know that the sum of all the angles in a regular pentagon is equal to 540° and the number of sides and the angles in a pentagon is 5.

Then the value of one angle is =540/5

=108°

Hence the internal angle of regular pentagon is 108° degree.
