Question

Steps to construct a 120 degree angle from 60 degree

Answer 1

This means that 120º is the supplement of 60º. Therefore, to construct a 120º angle, construct a 60º angle and then extend one of its arms as shown below.

Answer 2

Step-by-step explanation:

Use Ruler and draw a Line segment BC of any convenient length. (as shown below)

2). Now use compass and open it to any convenient radius. And with B as center , draw an arc which cuts line segment BC at Q . (as shown below)

3). Again use compass and opened to the same radius (as of step 2). And with Q as center , draw an arc which cuts first arc at R . (as shown below)

4). Again use compass and opened to the same radius (as of step 2). And with R as center , draw another arc which cuts first arc at P . (as shown below)

5). Join BP and extent it to A . (as shown below)

6) Above formed angle ABC = 120 Degree
