Hint: in a regular polygon interior plus exterior = 180o, always.

Exterior angle regular polygon = 360° ÷ number of sides = 360° ÷ W Interior angle regular polygon = 180° - exterior angle regular polygon = 180° - (360° ÷ number of sides ) = 180° - (360° ÷ W)

Each exterior angle of a regular polygon with n sides is 360/n degrees. Each interior angle of a regular polygon is 180 - Exterior angle. A direct formula for the interior angle is 180*(n-2)/n degrees.

Exterior = 36 degrees Interior = 144 degrees

If the polygon has n sides, each exterior angle is 360/n degrees.The interior angle is 180 less exterior angle.

A Regular Polygon

Square or rectangle

A quadrilateral.

Interior + Exterior = 180 and Interior = 5*Exterior So interior = 150 degrees and exterior = 30 degrees. Nothing more may be said unless it is known that the polygon is regular.

octagon interior=135 exterior=45

A regular polygon of 30 sides will each have an exterior angle of 12 degrees and an interior angle of 168 degrees.
