Step by step solution

01

Step 1. Given information.

The given angle is 120°.

02

Step 2. Follow the ways.

Consider the line segment AB¯.

With Aas centre draw an arc that intersects line AB¯at point Q.

Using the same radius and Qas centre draw an arc that intersect first arc at point R.

Using the same radius and Ras centre draw an arc that intersect first arc at point P.

Join the line segment role="math" AP¯
