Reviewing Transformations

Front

What is a reflection in geometry?

Back

A transformation that flips a shape over a line or axis.

Front

What does it mean to rotate a shape?

Back

To turn a shape around a fixed point by a certain angle.

Front

What is a translation in geometry?

Back

A transformation that slides a shape from one position to another without changing its size or orientation.

Front

Define dilation in geometry.

Back

A transformation that changes the size of a shape but keeps its proportions the same.

Front

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

Back

The y-coordinates of the points of the shape are inverted.

Front

What happens to a shape when it is rotated 90 degrees counterclockwise?

Back

The shape turns left around the center point by 90 degrees.

Front

Identify the transformation: A shape moves 3 units to the right and 2 units up.

Back

Translation.

Front

What is the effect of a 180-degree rotation on a shape?

Back

The shape is turned upside down.

Front

What is the difference between reflection and rotation?

Back

Reflection flips a shape over a line, while rotation turns it around a point.

Front

What does it mean to perform a transformation?

Back

To change the position, size, or orientation of a shape.
