Geometric Transformations

Front

What is a geometric transformation?

Back

A geometric transformation is a change in the position, size, or shape of a figure.

Front

Name the four main types of geometric transformations.

Back

Translation, Reflection, Rotation, Dilation.

Front

What is a translation in geometry?

Back

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

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is dilation in geometry?

Back

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

Front

What does it mean for two figures to be congruent?

Back

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

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped to create a mirror image.

Front

How does a translation affect the coordinates of a point?

Back

In a translation, each point of the figure moves the same distance in the same direction.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is turned.
