What is a geometric transformation?

Back

A geometric transformation is a function that moves or changes a shape in a specific way, such as translation, rotation, reflection, or dilation.

Front

Define translation in geometric transformations.

Back

Translation is a transformation that moves every point of a shape the same distance in a specified direction.

What is a rotation in geometry?

Back

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

Explain reflection in geometric transformations.

Back

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

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape by a scale factor, either enlarging or reducing it.

What does it mean for a transformation to preserve orientation?

Back

A transformation preserves orientation if the order of points in the shape remains the same after the transformation.

What is the effect of a dilation with a scale factor greater than 1?

Back

A dilation with a scale factor greater than 1 enlarges the shape.

What is the effect of a dilation with a scale factor less than 1?

Back

A dilation with a scale factor less than 1 reduces the shape.

Back

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