Draw a linear pair of angles.Bisect each of the two angles.Verify that the two bisecting rays are perpendicular to each other
Draw a straight line. Take a point P anywhere on the line. Now, draw the ray PA inclined at some angle to the straight line.
The angles marked form a linear pair.
Now, to learn how to draw the angle bisectors of these angles, go through the chapter 11, lesson 3.
After constructing the angle bisectors, measure the angle between the bisectors using a protractor. You will find that the bisectors are perpendicular to each other.
