Geometry Transformations Review

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What are the coordinates of a point after reflecting over the line y = x?

Back

The coordinates (x, y) become (y, x) after reflection over the line y = x.

Front

What happens to the coordinates of a point after a 180-degree rotation around the origin?

Back

The coordinates (x, y) become (-x, -y) after a 180-degree rotation around the origin.

Front

How do you translate a point in geometry?

Back

To translate a point, you add a specific value to the x-coordinate and a specific value to the y-coordinate.

Front

What is the result of reflecting a point over the x-axis?

Back

The coordinates (x, y) become (x, -y) after reflection over the x-axis.

Front

What is the result of reflecting a point over the y-axis?

Back

The coordinates (x, y) become (-x, y) after reflection over the y-axis.

Front

If point B (-4, -6) is reflected to create B' (4, -6), what type of reflection occurred?

Back

Reflection over the y-axis.

Front

What is the image of point A (-3, 1) after a reflection over the line y = x?

Back

(1, -3) is the image of point A after reflection over the line y = x.

Front

What are the coordinates of point K (-1, 6) after translating <2, 3> and then reflecting in the y-axis?

Back

The coordinates of K'' are (-1, 9) after the transformations.

Front

What is a rotation in geometry?

Back

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