What's your angle?

Angle: formed by two rays with the same endpoint

Vertex: the common endpoint of the two rays that form an angle (customary to name an angle by its vertex)

Types of Angles:

Straight: exactly 180°

Acute: less than 90°

Obtuse: more than 90°, less than 180°

Right: exactly 90°

Adjacent: share a common side and vertex, but do not overlap interiors

Vertical: created by intersecting lines which are pairs of angles whose sides are two pairs of opposite rays. They are congruent (exactly the same)!

Supplementary: two angles whose sum of measure is 180°

Since you are given 60°, you can solve

 angle WYZ by 180°-60°=120°

Complementary: two angles whose sum of measure is 90°

30°+60°=90°

Transversal: angles formed by a transversal line

 Line t is intersecting two coplanar lines l1 and l2. 

The line t is called the transversal.
