Introduction to Transformation

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 rotation in geometry?

Back

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

Front

Explain reflection 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 does a translation affect the coordinates of a shape?

Back

In a translation, the coordinates of each point of the shape are changed by adding a constant value to the x and y coordinates.

Front

What happens to a shape during a rotation?

Back

During a rotation, each point of the shape moves in a circular path around the center of rotation.

Front

What is the line of reflection?

Back

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

Front

How do you identify a rotation transformation?

Back

A rotation transformation can be identified by the angle of rotation and the center of rotation.
