1) Create a point A.[br]2) Reflect point A about the x-axis [br]3) Label the reflection point A' (right click on the point and choose '[b]Rename[/b]').[br]Next...[br]4) Create a point B at (1,2) and change the color of the point to red under the style bar[br]5) Reflect point B about the line y=x and change the color of the point to red under the style bar.[br]6) Label the reflection point B' (right click on the point and choose '[b]Rename[/b]').[br]Finally...[br]7) Create a point C on the line y=x and change the points color.
What is the coordinate for A'?
What is the coordinate for B'?
What do you notice about the distance from point B to the line of reflection and the distance from point B' to the line of reflection?[br][br]Do you think this observation holds true for all reflections of a point?
What happens if you reflect point C about the line it is on?
