Straight angles add to 180 degrees Exterior angle is equal to the sum of the two remote interior angles.
Use the distance formula simplify
Find the line that the 2 angles named are attached to. (transversal) Decide if they are:
Alternate exterior (outside angles that are on opposite sides of the transversal) Alternate interior (inside angles that are on opposite sides of the transversal) Corresponding (one exterior and one interior angle) Consecutive interior angles (both inside on same side of transversal)
