Question

what is the mrasurement of each interor angle if it is a regular polygon and find also the measurement of rach exterior angle?​

Answer 1

Answer:

Each interior angle =

(2n-4)×90°

n

(n = no. of sides)

Each exterior angle =

180°- each interior angle

Step-by-step explanation:

Example = Find each interior angle.

(Of a triangle)

=(2×3-4)×90°

=(6-4)×90°

=2×90°

=180°

Each interior angle = 180°

3

= 60°

Each exterior angle = 180°- 60°

= 120°
