Question

Which is different? Find "both" answers.

Answer 1

the one on the bottom right corner is different

Answer 2

Option A

Explanation:

We are given that a regular pentagon

We know that a regular pentagon is that type of figure in which is five equal sides and five equal angles.

The measure of an interior angle of a regular pentagon=
`108^(\circ)`

The sum of the interior angle measures of a regular pentagon=
`540^(\circ)`

We know that sum of interior angles measures of convex or concave polygon =
`180(n-2)^(\circ)`

n=5 then

The sum of interior angle measures of a convex pentagon =
`540^(\circ)`

The sum of interior angle measures of a concave pentagon=
`540^(\circ)`

Hence, the angle of measure of a interior angle of a regular pentagon is different from others.
