what is the interior and exterior angles of a regular polygon with 8 sides

Question

please help me with this question

Answer 1

Regular polygon have equal sides.

here sides n = 8

Exterior angle = 360/n

= 360/8

= 45

Interior angles = (n-2)*180/n

= (8-2)*180/8

= 6*180/8

= 1080/8

= 135

Interior angle is135degrees,Exterior angle is 45 degrees.
