P. 2 Grade 8 Transformations Practice 2024

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to create a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

Define rotation in geometry.

Back

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

Front

What does it mean to rotate a figure 90° counterclockwise?

Back

To rotate a figure 90° counterclockwise means to turn the figure 90 degrees to the left around the center of rotation.

Front

What is a line of reflection?

Back

A line of reflection is a line across which a figure is reflected to create a mirror image.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same size and shape.

Front

What is the effect of a dilation with a scale factor greater than 1?

Back

A dilation with a scale factor greater than 1 enlarges the figure.

Front

What is the effect of a dilation with a scale factor less than 1?

Back

A dilation with a scale factor less than 1 reduces the size of the figure.

Front

How do you determine the image of a point under a transformation?

Back

To determine the image of a point under a transformation, apply the specific transformation rules to the coordinates of the point.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated.
