Find the measure of each interior angle of 10 sided regular polygon.
Find the measure of each interior angle of 10 sided regular polygon. Solution. Verified by Toppr. Each interior angle of a polygon. = ( 2 n − 4 n) × 90 o. Here n = 10. ∴ Each interior angle = ( 2 × 10 − 4 10) × 90 o. = 144 o. Was this answer helpful?
