How to draw a right angle (perpendicular line) and a rectangle

I show how you can draw a right angle (or a perpendicular line to a given line) using either a protractor or a triangular ruler. I also show a line perpendicular to a given line, drawn through a point on the line, or drawn through a point not on the line.

Lastly, I draw a rectangle with given side lengths, using a protractor to make right angles, and a regular ruler to measure the sides.
