Question

if angle a is congruent to angle b and angle x is congruent to angle y then prove line l is parallel to line n​

Answer 1

Answer:

Two angles are congruent if they have the same measure. You already know that when two lines intersect the vertical angles formed are congruent. You have also seen that if ∠A and ∠B are each complementary to ∠C, then ∠A ~= ∠B.
