What is a reflection in geometry?

Back

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

What does it mean for figures to be congruent?

Back

Congruent figures have the same shape and size, meaning they can be superimposed on each other.

What is the difference between translation and reflection?

Back

Translation slides a figure without changing its orientation, while reflection flips it over a line.

What is the effect of a translation on the coordinates of a point?

Back

The coordinates of a point are adjusted by adding or subtracting values based on the direction and distance of the translation.

What does it mean for translations to be congruent?

Back

Translations are congruent because they preserve the shape and size of the figure.
