Unit 1 Catchup Plan

Front

What are rigid transformations?

Back

Rigid transformations include translations, reflections, and rotations that create congruent figures.

Front

What does it mean for figures to be congruent?

Back

Congruent figures have the same size and shape.

Front

What happens to the size and shape of a figure during a rigid transformation?

Back

The size and shape remain the same.

Front

What is a translation in geometry?

Back

A translation is a transformation that moves a figure up, down, left, or right without changing its shape or size.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

How do you label a new figure after a transformation?

Back

The new figure is labeled with a prime symbol (') after the original label, e.g., M becomes M'.

Front

What does the notation M' signify?

Back

M' signifies the new figure after a transformation of the original figure M.

Front

If a figure is translated up 2 and right 4, what is the transformation?

Back

The transformation is a translation that moves the figure 2 units up and 4 units to the right.

Front

What is the result of reflecting a figure over the x-axis?

Back

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