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.
I used a protractor to find the measure of the angle.
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.
To measure an angle accurately, use a protractor. Place the center of the protractor at the vertex of the angle. Align one side of the angle with the 0-degree mark on the protractor. Read the measurement where the other side of the angle intersects the protractor.

To accurately measure angles using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the zero line on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.
To use a protractor effectively for measuring angles, place the center of the protractor on the vertex of the angle. Align one side of the angle with the 0-degree mark on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.
To measure an angle on a wall accurately, use a protractor. Place the protractor on the corner of the angle and align the baseline with one side of the angle. Read the measurement where the other side of the angle intersects the protractor. This will give you the accurate measurement of the angle.
