WebApr 9, 2024 · Now, the formula to find the interior angle of a regular decagon is given by. → Interior angle = 180 − exterior angle. Now, as we found that each exterior angle of a regular decagon is 36, its interior angle will be. → Interior angle = 180 − 36 = 144 ∘. Hence, a regular decagon has each exterior angle 36 ∘ and each interior angle as ... WebNov 8, 2010 · 144o. Sum of exterior angles of a polygon is 360o. Each exterior angle for a regular decagon is 360o / 10 = 36o. Exterior and interior angles are supplementary, that is sum to 180o. Therefore the interior angle of a regular decagon is 180o - 36o = 144o.
