PROTRACTOR WORKSHEET

• This worksheet goes with:   Segments, Rays, Angles
• This worksheet prints out on two pages.

First, study these web animations:

Use a protractor to measure the specified angles in the diagram above:
the measure of $\,\angle BAC\,$ is __________	the measure of $\,\angle CAD\,$ is __________	the measure of $\,\angle BAD\,$ is __________
Two of your angle measures should sum to the third. Check that this is true:

Using the diagram below: Use your protractor to draw a $\,37^{\circ}\,$ angle with vertex $\,A\,$ and with $\,\overrightarrow{AB}\,$ as one of its sides. Label a point $\,C\,$ on the other side of the angle you just drew. Use your protractor to draw a $\,49^{\circ}\,$ angle with vertex $\,A\,$ and with $\,\overrightarrow{AC}\,$ as one of its sides.
