# Reflections in the Coordinate Plane APS

1) Plot the points (

**type**the ordered pair into the**input bar**, bottom of the page)**2) A(-3,2), B (-1,4) and C (-5, 3)**3) Use the polygon tool to construct the triangle ABC**4)**Use the reflection tool (9th tool over, under the reflection diagram) 5) Select the**Triangle ABC, then y-axis**When you're done (or if you're unsure of something), feel free to check by watching the quick silent screencast below the applet.

## Video (silent video)

What are the coordinates of A'B'C'?

## 2.

1) Plot the points (

**type**the ordered pair into the**input bar**, bottom of the page)**2) A(5,-1), B (3,-1) and C (4, -3)**3)Use the polygon tool to construct the triangle ABC**4)**Use the reflection tool (9th tool over, under the reflection diagram) 5) Select the**Triangle ABC, then x-axis**List the points of A"B" and C"

If a Triangle is in quadrant 2, and we reflect it over the **x_axis **which quadrant would the image be in?
