Front

What is Dilation?

Back

Dilation means to enlarge or reduce.

Front

Which rule would result in a translation of 2 units left and 3 units up?

Back

(x, y) → (x - 2, y + 3)

Front

What are figures that have the same shape but not necessarily the same size called?

Back

Similar figures.

Front

What is the rule for the dilation that doubles the size of a figure?

Back

(x, y) → (2x, 2y)

Front

Identify the transformation from ABCD to A'B'C'D' if it moves without changing shape or size.

Back

Translation.

Front

What does a reflection transformation do?

Back

It flips a figure over a line, creating a mirror image.

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point.

Front

What is the difference between congruent figures and similar figures?

Back

Congruent figures are the same size and shape; similar figures have the same shape but different sizes.

Front

What is the transformation rule for a reflection across the y-axis?

Back

(x, y) → (-x, y)

Front

What is the transformation rule for a 90° counterclockwise rotation?

Back
