Angle, Two different rays that have the same initial point. Acute, An angle Vertical angles, Two angles whose sides form two pairs of opposite rays. Linear pair.
A Linear Pair is two adjacent angles whose non-common sides form opposite rays. linearpair. ∠1 and ∠ 2 form a linear pair. The line through points A, B and C.
Two rays are opposite rays in geometry if they have a common initial point and form a straight line. Essentially, these rays point in opposite directions.
