Suppose q and r are two lines intersected by transversal t. If one of the angles formed by q and t is congruent to every angle formed by r and t, which would be true? r is parallel to t? q is perpendicular to r? q is parallel to t or is r perpendicular to t? I am having some problems figuring this question out. If any body is good at geometry it would be very appreciated if somebody could help me out! Thanks.
