Question

If interior angle of a regular octagon is 135⁰, then find the external angle of it. *
​

Answer 1

A regular octagon, then yes each interior angle is 135 degrees. ... 360/8 = 45 degrees. Since the exterior angles and the interior angles are supplementary, add to 180 degrees,

180 - 45 = 135 degrees.

Answer 2

Answer:

regular octagon has 8 equal sides and 8 equal angles calculate the size of each interior angle in the regular octagon we do this by subtracting the size of each interior angle is 45 degree from 180 degrees the answer is 180 degrees minus 45 degrees is equals to 135 degrees
