Transformations

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

Define translation in geometry.

Back

Translation is a transformation that slides a shape from one position to another without turning it.

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

Front

What does reflection mean in geometry?

Back

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

Front

What is dilation in geometry?

Back

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

Front

How do you identify a 90° clockwise rotation?

Back

A 90° clockwise rotation turns a shape to the right around a point.

Front

What is the difference between clockwise and counter-clockwise rotation?

Back

Clockwise rotation goes in the direction of a clock's hands, while counter-clockwise rotation goes in the opposite direction.

Front

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

Back

Reflecting a shape across the x-axis flips it vertically, changing the sign of the y-coordinates.

Front

What happens when you translate a shape 5 units to the right?

Back

The x-coordinates of all points in the shape increase by 5.
