Adjacent Angles: Angles that share the same origin and are side by side are called adjacent angles.
In the example below Angle CDB and Angle BDA are adjacent angles.

Vertical Angles: Angles that share the same origin and are opposite to each other are vertical angles.
In the example below Angle AVC and Angle BVD are vertical angles.

Supplementary Angles: Two angles that sum up to 180° are called supplementary angles.
In the example below Angle AVC and Angle AVB are supplementary angles.

Complementary Angles: Two angles that sum up to 90° are called complementary angles.
In the example below Angle CDB and Angle BDA are complementary angles.
