A. Vertical angles.
Complementary angles are adjacent angles that add to equal 90 degrees.
Adjacent angles are angles that share a side (they are right next to each other).
Supplementary angles are adjacent angles that add to equal 180 degrees.
Thus the answer is A.
Hope this helps.
1 x 10^-8 or .1 nanometer (nm)
Opposite angles of a cyclic quadrilateral add up to 180 degrees so m<R = 180-92 = 88 and m < S = 180-92 = 88 degrees also
m< R = m< S Answer
