I hope this helps you

Answer 2

Adjacent angles : If two angles have a same vertex and one common side and the angles are situated in different sides of the common arm, they are called adjacent Angeles.

Supplementary angles: If the some of measurement of two angles is 180°, or two right angles then they are called supplementary angles to each other.

Complementary angles: If the some of two angles is 90°, or one right angle then they are called complementary angle to each other.
