Activity 1 Angle Relationships

Identify adjacent, complementary, and supplementary angles.

Adjacent angles have a common vertex and ray. They are angles that
are formed side by side.

J HIJ and JIK are
H adjacent angles.

IK HIJ and HIK are not
adjacent angles.

Complementary angles are 2 angles whose measures add up to 90 .

M O P MNO and PQR are
Q complementary angles.
60 30
N R m MNO + m PQR
= 60 30
= 90

Supplementary angles are 2 angles whose measures add up to
180 .

V STU and VWY are
supplementary angles.
