Reflections in the Coordinate Plane
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.

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

Use the reflection tool (9th tool over, under the reflection diagram)
5) Select the Triangle ABC, then x-axis

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