Transformations Basics

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 moves every point of a shape the same distance in the same direction.

Front

What is a rotation?

Back

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

Front

Define reflection in geometry.

Back

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

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is rotated.

Front

How do you identify a rotation in a transformation?

Back

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

Front

What is the difference between reflection and rotation?

Back

Reflection flips a shape over a line, while rotation turns a shape around a point.

Front

What does it mean to rotate a shape 90 degrees clockwise?

Back

Rotating a shape 90 degrees clockwise means turning the shape 90 degrees to the right around the center of rotation.

Front

What is the effect of a translation on a shape's orientation?

Back

A translation does not change the shape's orientation; it only changes its position.
