Copy of Transversals and Parallel Lines

Transversals and Parallel Lines

1) How many parallel lines are in the diagram?

2) What do you notice about the third line? ( is it parallel? does it intersect the other lines? is it perpendicular?)

3) Name three pairs of angles that are supplementary (both angles add up up to 180 degrees)

4) Name four pairs of congruent angles (the angles have the same measurement)

5) Name the two parallel lines using two points

6) Name the transversal line using two points

7) Use the arrow to move the transversal line around. Are the angles you listed in question four still congruent?

8) Name all the vertical angles in the picture.

9) Name a pair of alternate interior angle. Name a pair of alternate exterior angles.

10) Name a pair of consecutive interior angles. Name a pair of consecutive exterior angles.
