What is reflection in geometry?

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What does the scale factor in dilation represent?

Back

The scale factor indicates how much larger or smaller the dilated shape is compared to the original shape.

If a shape is dilated by a scale factor of 2, what happens to its size?

Back

The shape becomes twice as large as the original shape.

How do you determine the scale factor when given original and dilated points?

Back

Divide the coordinates of the dilated point by the corresponding coordinates of the original point.

What is the result of a reflection across the x-axis?

Back

The y-coordinates of the points change sign, while the x-coordinates remain the same.
