Back

(2, 5)

Front

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

Back

(x, y) → (x - 2, y + 3)

Front

Describe the transformation: (x-2, y+7)

Back

Front

What is a translation in geometry?

Back

A transformation that moves every point of a figure the same distance in a given direction.

Front

What is the effect of reflecting a point across the y-axis?

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

What is the rule for a reflection across the x-axis?

Back

(x, y) → (x, -y)

Front

What does it mean for a transformation to preserve congruence?

Back

The shape and size of the figure remain unchanged after the transformation.

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape.
