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.
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.
These are the steps to construct a perpendicular.
