What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

What does the rule (x-6, y+8) represent?

Back

It represents a translation where each point of the figure is moved 6 units left and 8 units up.

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 (x, y) when it is reflected across the x-axis?

Back

The coordinates become (x, -y).

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure, either enlarging or reducing it, while maintaining its shape.

What is the center of dilation?

Back

The center of dilation is a fixed point in the plane about which all points are expanded or contracted.

What is the difference between a translation and a reflection?

Back

A translation moves a figure without changing its orientation, while a reflection flips it over a line.
