A tip of a pen shows centre of the protractor.

Measure the angle shown in picture.

Step:01

Put the centre of the protractor on the vertex Q of an angle.

Step:02

The angle is measured starting fromvthe zero on that side of the vertex on which the arm of the angle lies.

Here side QR is on the right of the vertex Q . 

Therefore,count thevdivisions starting from the zero on the right.

see which mark falls on arm QP.

Read the number on that mark.

This is the measure of the angle.
