Line segment. Distance between two points.
Line. Opposite directions infinitely.
Ray. Goes in one direction infinitely.
Point. A location.
Angle. Two rays that share a common vertex.
Vertex. The corner of an angle or shape.
Legs. Another way to say the sides or rays of an angle.

22 + 36 + 32 =
These angles are complementary

EXAMPLESSupplementary Angles
• Two or more angles whose sum is 180
90
33
57
These 3 angles are supplementary
90 + 33 + 57 = 180

Triangle angles are supplementary.
ALWAYS.
Because all 3 angles will ALWAYS add to 180°.
