Similarity and Transformations

Front

What are matching sides in similar figures called?

Back

Corresponding Sides

Front

What is a dilation in transformations? Give an example.

Back

A dilation is a transformation that changes the size of a figure but not its shape. Example: (x, y) → (3x, 3y) is a dilation.

Front

What is the sequence of transformations: Reflect across the x-axis and then rotate -90 degrees around the origin?

Back

This describes a specific sequence of transformations applied to a figure.

Front

What are matching angles in similar figures called?

Back

Corresponding Angles

Front

True or False: All angles in similar figures are congruent.

Back

True

Front

What is the definition of similarity in geometry?

Back

Similarity in geometry means that two figures have the same shape but may differ in size.

Front

What is a transformation in geometry?

Back

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

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but different sizes.

Front

What does it mean to reflect a figure across an axis?

Back

To reflect a figure across an axis means to create a mirror image of the figure over that axis.

Front

What is a rotation in geometry?

Back

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