The answer to your question is (C) VERTICAL ANGLES
When 2 lines intersect, they make
vertical angles.
Vertical
angles are congruent (equal).
Vertical
angles are opposite one another.Supplementary angles add up to 180º = 40 degrees + 140 degrees = 180 degrees.
Adjacent
and Supplementary Angles = 120 + 60 = 180 degreesAdjacent angles are “side by side”
and share a common ray. 130 degrees and 50 degrees.Complementary angles add up to 90º. = 60 degrees + 30 degrees = 90 degrees.
