Part II

Complete the following exercises

1. Given ΔABC in the following graph, use coordinate geometry to plot its image under a

a) Translation using the given slide arrow.  Explain your thinking.

b) Reflection using the given mirror.  Explain your thinking.

2. Describe a transformation that would “undo” the translation described in exercise #1.  Undo the reflection. 

3. If one transformation undoes another, the two transformations are said to be inverses of one another.  Create pairs of inverse transformations, each of which is a …
