Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

What happens to the coordinates of a point when it is reflected over the x-axis?

Back

The y-coordinate changes sign, while the x-coordinate remains the same.

If point B(-1, 5) is reflected over the y-axis, what are the coordinates of B'?

Back

B' will be (1, 5).

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected, creating a mirror image.

How do you reflect a triangle over the x-axis?

Back

To reflect a triangle over the x-axis, change the sign of the y-coordinates of each vertex.
