Parallel and Perpendicular lines - School District 43 ...
www.sd43.bc.caThe two slopes are equal , the two lines are parallel. Also the two lines are horizontal e. m1 = ( 7 - 5 ) / ( -2 - (-2) ) m2 = ( 13 - 1 ) / ( 5 - 5 ) The two slopes are both undefined since the denominators in both m1 and m2 are equal to zero. The two lines are vertical lines and therefore parallel. Solution to Q6: No.

The other one will always be shallower slope (smaller apparent dip). Figure 11: A: Plane is seen in a cross section which is cut perpendicular to the strike of the plane (parallel to, or containing, the line of true dip).
