. How to construct Angles by using Protector?
An angle can be constructed either with the help of a protractor and a ruler or a compass and a ruler. Let us construct a 50° angle using a protractor.
Step 1: Draw a line segment OA.
Step 2: Place the middle of the protractor at point O.
Step 3: Start from point A from the clockwise direction and at 50 degrees mark a point by looking at the outer circle of the protractor. Mark this point as B.
The ∠BOA is the required 50° angle.
