Name the vertex of angle 4

The vertex is the point that the rays meet at. Find angle 1, then find the letter that is there.

Name the sides of angle 3

What is another name for angle 2?

Hint: to name an angle you will put the vertex in the middle. Find angle 2, the point there is the vertex and must go in the middle.

What is another name for angle UXY?

Hint: find angle UXY, then use the number where the X is at.

Hint: angle NKM & angle LKN are congruent, so they have the same measure.
