Question

Explain the properties of a figure that are preserved under a translation, reflection, or a rotation.

Answer 1

When a figure undergoes a translation, a rotation or a reflection, the new figure is congruent. This means the size and shape of the figure does NOT change.

So the properties that are preserved are its size and shape.

Answer 2

Shape and Size.

Explanation:

When we talk about transformations like translations, reflections or rotations, we are referring to rigid transformations, which doesn't change the shape or size of the figure, that's why is called rigid.

Therefore, the properties of a figure that doesn't change with translations, reflections or rotations are shape and size.
