Answer 1

1. We know that , Sum of exterior angles of any polygon is 360° ....

2. Yes .

Since , it is a regular hexagon ...

3. (i) Each Exterior Angle = 360°÷6 = 60°

(ii) Each Interior Angle = Exterior Angle + Interior Angle where the angles are in linear pair .

=> Each Interior Angle = 180°-60° = 120° ...

4. (i) A REGULAR OCTAGON

Each Exterior Angle = 360°÷8 = 45°

Each Interior Angle = 180°-45° = 135°

(ii) A REGULAR 20-GON

Each Exterior Angle = 360°÷20 = 18°

Each Interior Angle = 180°-18° = 162°
