Answer to Problem 22RP

Octagon is concave.

Explanation of Solution

Given:

The sum of the measures of five of angles of an octagon is 540 .

Calculation:-

The sum of all the angles of octagon is =(8−2)×180=1080 .

The sum of 5 angles is 540 .

And then the other three angles sum is 1080−540=540

This means all angles are 180∘ and it means the octagon is concave.
