Solution
The correct option is A Ruler
With the help of a ruler, we can draw roughly perpendicular lines, but we can’t be sure that the lines will be exactly perpendicular.
We get lines that are perfectly perpendicular with the help of a set square.
Placing the protractor on a line drawn using a ruler, we can mark 90 degrees and on joining that point with the vertex of the angle, we get a perpendicular line.
With the help of a compass, we can construct the perpendicular bisector to a line segment or construct a 90 degrees angle. Either way, we get a perpendicular line.
