Let's say here are your three lines: |||. and there's a transversal that goes vertically through them: |||-. if the transversal goes through one line and creates a 90 degree angle it's a straight line so that means it's going to pass through all three making the same angles on all three lines. therefore the answer is D, all the angles are 90 degrees.
