CP Geometry Transformation Review

Front

What is the mathematical term for the line that you reflect a shape over?

Back

Line of reflection

Front

What series of transformations includes a rotation of 90 degrees clockwise and a reflection over the x-axis?

Back

Rotation 90° clockwise, reflection over the x-axis

Front

If point H(–6, 2) is translated 3 units right and 4 units up, what are the new coordinates?

Back

(-3, 6)

Front

What are the coordinates of point N(6, –5) after being reflected across the x-axis?

Back

(6, 5)

Front

What are the coordinates of point R after a 90-degree clockwise rotation?

Back

(3, -3)

Front

Define translation in geometry.

Back

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

Front

What is a reflection in geometry?

Back

A transformation that flips a shape over a line, creating a mirror image.

Front

What does a 90-degree clockwise rotation do to the coordinates of a point (x, y)?

Back

It transforms the point to (y, -x).

Front

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

Back

The x-coordinate changes sign, resulting in (-x, y).

Front

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

Back

The y-coordinate changes sign, resulting in (x, -y).
