A "protractor" is a device that can be used to draw angles of a specified size,
or measure the size of unknown angles, in the same way that a "ruler" is used
to do the same thing with lines.
Place the center point of the protractor at the vertex of the angle and one of the lines of the angle along the zero line of the protractor. The measure of the angle will then be where on the protractor's angular scale the other line of the angle lies.

A protractor is an instrument that is used when you need to measure an angle.

a protractor is used to measure an angle
An angle ruler is a tool used to measuring angles like a protractor. An angle ruler is more accurate than a protractor.

To measure ans angle, put the hole on the the vertex, line up the protractor with the angle and look at the degrees.
You don't always need a protractor to make an angle, just use a normal ruler.
