Unit 1 Catchup Plan

Front

What is reflection in geometry?

Back

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

Front

What is a reflection over the x-axis?

Back

A reflection over the x-axis means that each point of the figure is flipped to the opposite side of the x-axis.

Front

What is a reflection over the y-axis?

Back

A reflection over the y-axis means that each point of the figure is flipped to the opposite side of the y-axis.

Front

What are rigid transformations?

Back

Rigid transformations are movements of figures that preserve their size and shape, including translations, reflections, and rotations.

Front

What does it mean for figures to be congruent?

Back

Congruent figures are figures that 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 during a rigid transformation.

Front

What is a translation in geometry?

Back

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

Front

How do you perform a translation on the coordinate plane?

Back

To perform a translation, take the point (or the corners of a shape) and count the number in the direction it states.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What does a 90º clockwise rotation mean?

Back

A 90º clockwise rotation means turning the figure 90 degrees in the direction of the clock's hands.
