Answer 8

they aren't true because they don't have the 90 degree angle symbol

Answer 9

remember, if two lines are perpendicular they will create 90 degree angles. there doesn't need to be a 90 degree symbol.

Answer 10

so they are both correct?

Answer 11

which two? A and C? no, A is correct, C is not. either B or D is correct. check the diagram to see which angle is created by two perpendicular lines.
