Interior angle :-

A regular octagon has 8 sides, so:

Exterior Angle = 360° / 8 = 45°

Interior Angle = 180° − 45° = 135°

Or we could use:

Interior Angle = (n−2) × 180° / n

= (8−2) × 180° / 8

= 6 × 180° / 8

= 135°

Exterior angle :-

An octagon has 8 sides, so:

Exterior angle = 360° / n

= 360° / 8

= 45°
