Front

What is the result of reflecting a polygon across the y-axis?

Back

The x-coordinates of the vertices of the polygon change sign, while the y-coordinates remain the same.

Front

What is the measure of angle Y' if polygon UVWXY is reflected across the y-axis and the original angle Y is 136 degrees?

Back

Angle Y' measures 136 degrees.

Front

What happens to the angle measures of a quadrilateral when it is translated horizontally?

Back

The angle measures remain unchanged.

Front

If quadrilateral KLMN is translated horizontally, what is the measure of angle N' if angle N is 40 degrees?

Back

Angle N' measures 40 degrees.

Front

What is the effect of translating a shape on its dimensions?

Back

Translation does not change the dimensions or angles of the shape.

Front

What is the relationship between two lines with equal slope after they are translated?

Back

The lines remain parallel.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the result of reflecting a shape across the x-axis?

Back

The y-coordinates of the vertices change sign, while the x-coordinates remain the same.

Front

If parallelogram QRST is translated 10 units right and reflected across the x-axis, what happens to the lengths of its sides?

Back

The lengths of the sides remain the same.

Front

What is the definition of a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length.
