Unit 7 Review Pt 2

Front

What is the rule for a rotation of 90 degrees clockwise or 270 degrees counterclockwise?

Back

The coordinates (x, y) transform to (y, -x).

Front

What type of transformation is a translation?

Back

A translation moves a shape a certain distance in a specified direction without changing its size or orientation.

Front

What is the rule for a rotation transformation?

Back

A rotation turns a shape around a fixed point by a certain angle.

Front

What is the rule for reflection over the X-axis?

Back

The coordinates (x, y) transform to (x, -y).

Front

What is the rule for reflection over the Y-axis?

Back

The coordinates (x, y) transform to (-x, y).

Front

What is the rule for a rotation of 180 degrees?

Back

The coordinates (x, y) transform to (-x, -y).

Front

What is dilation in transformations?

Back

Dilation changes the size of a shape while keeping its proportions the same.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips a shape over a line.

Front

What does it mean to translate a shape 3 units right and 2 units up?

Back

The coordinates (x, y) transform to (x + 3, y + 2).

Front

What is the effect of a 90-degree counterclockwise rotation on the coordinates (2, 3)?

Back

The coordinates transform to (-3, 2).
