SOLUTION
Vertical angles are angles that are formed opposite each other when two lines cross. No two lines are crossed here to form angles a and b to face e chother,.
Hence angles a and b are not vertical angles
Complementary angles are angles that add up to 90 degrees. They are formed when the angle 90 degrees is divided to orm two angles. aAngles a and b are not formed in such case here,
Hence angles a and b are not complementary angles.
Supplementary angles are angles on a straight-line that add up to 180 derees .
Angles a and b do not add up t 1080 degrees, hence are not supplementary.
Hence theanswer is nNone of the above, option D
