Reflection of a Triangle

Investigate what happens to the triangle when it is reflected using the checkboxes.

Answer the following questions:
1.) If the point (2, 3) is reflected over the x-axis what is the new point?

2.) If the point (-4, 6) is reflected over the y-axis what is the new point?

3.) Answer the following questions without using the checkboxes. If the coordinates of triangle ABC are A=(1, 2), B=(4, 3), and C=(3, 6) what are the vertices of the triangle reflected over the x-axis? Over the y-axis? Now use the checkboxes to see if you are correct.

4.) Write a rule for reflecting a point over the x-axis.

5.) Write a rule for reflecting a point over the y-axis.
