Construction of Perpendicular Lines by Using a Protractor

Construction of perpendicular lines by using a protractor is discussed here.

To construct a perpendicular to a given line l at a given point A on it, we need to follow the given procedure for constructing an angle of 90° at A.

Steps of construction:

Steps of construction

1. Let l be the given line and A the given point on it.

2. Place the protractor on the line l such that its base line coincides with l, and its centre falls on A.

3. Mark a point B against the 90° mark on the protractor.

4. Remove the protractor and draw a line m passing through A and B.

Then line m ┴ line l at A.
