Define translation in geometry.

Back

A translation is a type of rigid transformation that slides a figure from one position to another without changing its shape, size, or orientation.

What is a reflection in geometry?

Back

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

What is the algebraic representation of a translation 5 units right and 9 units down?

Back

The algebraic representation is (x, y) → (x + 5, y - 9).

How do you reflect a point across the x-axis?

Back

To reflect a point (x, y) across the x-axis, the new coordinates become (x, -y).
