Angle is the measurement of rotation, with the way the terminal axis rotated. The given angles are adjacent angles and supplementary angles both.
Two angles are called adjacent angles if they share a common side.
Two angles whose sum is 90° are called complementary angles.
Two angels whose sum is 180° are called supplementary angles.
Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
In the figure attached below, it is visible that the angles 1 and 2 are such that they are sharing a side. Thus, they are adjacent angles.
Also, as we add those angles, we see that a straight line is formed (which is of 180° always), thus, they are supplementary angles too.
Hence, the given angles are adjacent angles and supplementary angles both.
