3-2 Properties of Parallel Lines
Corresponding Angles
Draw two parallel segments and a transversal and label the points of intersection. Find the measure of two corresponding angles. (Make them GREEN)
NOTE: To measure an angle be sure that you have points on both rays of the angle.
Alternate Interior Angles
Draw two parallel segments and a transversal and label the points of intersection. Find the measure of two alternate interior angles. (Make them GREEN)
NOTE: To measure an angle be sure that you have points on both rays of the angle.
Same-Side Interior Angles
Draw two parallel segments and a transversal and label the points of intersection. Find the measure of two same-side interior angles. (Make them GREEN)
NOTE: To measure an angle be sure that you have points on both rays of the angle.
Find the measure of two other corresponding angles. (Make them BLUE) What did you discover about corresponding angles?
