Answer 1

Answer:

pls mark as brainliest plsss

Step-by-step explanation:

Draw a line segment BC, which is one of the arms of the angle that is to be constructed.

Constructing Angles Using a Protractor - Step 1

Place the protractor with its point O on the point B of the line segment BC.

Constructing Angles Using a Protractor - Step 2

Align OQ along the edge BC.

The protractor has two-way markings. We consider the scale which has 0 degrees near point C for construction. Mark point A next to the 120 degrees mark on the scale.

Constructing Angles Using a Protractor - step 4

Join points A and B. ∠ABC = 120 degrees is the required angle.
