Jamal’s teacher gave him the following figure and asked him to provide a statement that would guarantee lines a and b are parallel. Which statement should Jamal use to prove that lines a and b are parallel? ∠7 = 120° ∠2 = 60° ∠4 = 60° ∠3 = 120°
For the two to be parallel, each of the corresponding angles would need to be equal
Its actually quite simple given the choices you have, as angles 2 3 and 4 are all related to line a. So angle 7 = 120 is the answer just by process of elimination
But the reasoning would be that angle 3 and the given angle are equal and angle 7 corresponds to angle 3
