Question

what is the ratio of interior and exterior angles of a regular octagon​

Answer 1

Answer:

We know that the sum of the exterior angles of any polygon in existence is equal to 360°. We also know that the sum of an exterior angle +its interior angle=180°. Answer-3:1 is the ratio of an angle of a regular octagon to its exterior angle.

Answer 2

Answer:

The exterior angle of a regular octagon = 360/8 = 45 deg and so each interior angle = 180–45 = 135 deg.

So the ratio of the interior angle to the exterior angle of a regular octagon is 3:1
