Angles that add up to $$90^\circ$$

Angles that are opposite each other when two lines cross

Angles that are next to each other and share a side

Angles that add up to $$180^\circ$$

$$90^\circ$$

$$120^\circ$$

$$180^\circ$$

$$360^\circ$$

Supplementary angles

Complementary angles

Vertical angles

Adjacent angles

They are equal in measure

They are on opposite sides of a transversal

They share a common vertex and a common side

They add up to $$180^\circ$$

$$x + y = 90$$

$$x + y = 180$$

$$x = y$$

$$x - y = 90$$
