Core 8 - Congruent and Similar Figures

Front

What are congruent figures?

Back

Congruent figures are shapes that are the same shape and the same size.

Front

What does it mean for two figures to be similar?

Back

Similar figures have the same shape but may differ in size. Their corresponding angles are equal, and their sides are in proportion.

Front

What is the reflection of a figure?

Back

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

Front

What is the difference between enlargement and reduction?

Back

Enlargement increases the size of a figure, while reduction decreases the size of a figure.

Front

How do you identify corresponding angles in similar figures?

Back

Corresponding angles in similar figures are angles that are in the same relative position.

Front

What is the significance of the y-axis in reflections?

Back

Reflecting a figure over the y-axis means that each point of the figure is mirrored across the y-axis.

Front

What is the significance of the x-axis in reflections?

Back

Reflecting a figure over the x-axis means that each point of the figure is mirrored across the x-axis.

Front

How can you determine if two shapes are similar?

Back

Two shapes are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.

Front

What does it mean for two shapes to be neither similar nor congruent?

Back

Two shapes are neither similar nor congruent if they do not have the same shape or size, and their corresponding angles and sides are not proportional.
