Measuring Exterior Angles
Can you make an interesting discovery...or two?
What do you notice about the measure of and the measure of the adjacent, exterior angle?
That was too easy. Now, allowing for a bit of rounding error in the hundredths place of the angle measures, write a hypothesis about the relationship between the exterior angle and the two angles that are not adjacent to that angle.
Is there a connection between your two observations? If so, what? Compare your thoughts with a neighbor before recording in your notes.
