Describe in words how to use a protractor to measure angles.
You need to line up the origin with the vertex of the angle. The bottom ray needs to be lined up with the bottom of the protractor. Look at which direction the ray is pointing towards. If it is pointing to the right, look at the bottom set of numbers. If it is pointing to the left, look at the top set of numbers. Look at where the top ray goes through the protractor and identify what the measurement is.
