Question

Assume the two lines ↔AB and ↔XY intersect as in the diagram below. Which of the following statements are true?

Check all that apply.

Answer 1

A and B are true because if there is a 90 angle for two intersecting lines, then the two lines are perpendicular. As well, vertical angles are the angles opposite of one another and these angles are opposite sides. Complimentary means they add up to 90 and supplementary angles add up to 180
