PROTRACTOR WORKSHEET

First, study these web animations:

Animation: Using a Protractor to Draw an Angle at: http://www.mathopenref.com/constdrawangle.html

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.
