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

Translation, rotation, reflection, and dilation.

Front

What does translation mean in the context of transformations?

Back

Translation means moving a shape from one location to another without changing its size, shape, or orientation.

Front

What is a reflection in geometry?

Back

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

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

What does it mean for two shapes to be congruent?

Back

Two shapes are congruent if they have the same size and shape.

Front

What is the term for rotating a shape to the right?

Back

Clockwise.

Front

What is the term for rotating a shape to the left?

Back

Counter-clockwise.

Front

What is a dilation in geometry?

Back

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

Front

What is the effect of a translation on the size and shape of a figure?

Back

A translation does not change the size or shape of a figure; it only changes its position.
