- Reflection or Reflexion
In this applet, you will test your understanding of reflection. The brown triangle is the original triangle and the green triangle will be used to place the image of the original triangle. You have four lines of reflection choices. You can reflect the original triangle over the x-axis, the y-axis, the line for y=x, and the line for y=(-x). So click on one of the four choices. Then move the brown triangle on the grid. Next move the green triangle to the place where you believe the reflection of the original triangle would fall. Then click on the REFLECTION button to check your answer. Attempt each line of reflection (the x-axis, the y-axis, the line for y=x, and the line for y=-x) until you get 5 problems correct.
