Describe two different ways to name an angle formed by points A, B, and C, where B is the vertex.
<B, <ABC, <CBA
Reflect triangle ABC with A(3,-1), B(1,-5), and C(-2,-2) in the x-axis. What are the coordinates of B?

Define what a rigid motion is.
Rigid motions produce congruent figures.
Ex: Reflection, Translation, Rotation

Explain why it is important to place the vertex letter in the middle when naming an angle.
So you know that the letter in the middle is the vertex.

Define what a dilation is.
Dilation is a non-rigid motion that produces similar figures.

What is another way to name an angle besides using three points?
Using the number of the angle.
