Question

Construct an angle of 30° using compasses and ruler .Now construct an angle of measure 15° using compasses

Answer 1

Construct an angle of 90° using compass and ruler then bisect them using the same.

This will give an angle of 30° and again bisect it using the same procedure done before, which will give an angle 15°.

Answer 2

first construct 60° using compass and ruler which is a special angle. bisect the angle then it becomes 30° . again bisect the angle then it becomes 15°. name the angles . thus angle EAC is equals to 15°
