How would we prove the lines are parallel?
Given: angle2 cong angle6
If two lines are cut by a transversal and the corresponding angles are congruent, then the lines are parallel.

ALL PLAY:
What 2 facts do we need to prove a perpendicular bisector?
1. The intersecting lines form a midpoint
2. At least, one right angle is formed.
200
Are the two equations Parallel or Perpendicular? EXPLAIN.
y= 1/2x +10 and y=-2x+10
Perpendicular, because the slopes are negative reciprocals of each other.
