What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce a new shape, called the image.

What is a translation?

Back

A translation is a transformation that moves every point of a shape the same distance in the same direction.

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.

What is a reflection?

Back

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

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same, defined by a scale factor.

What does a scale factor greater than 1 indicate?

Back

A scale factor greater than 1 indicates an enlargement of the shape.

What does a scale factor less than 1 indicate?

Back

A scale factor less than 1 indicates a reduction of the shape.

What is line symmetry?

Back

Line symmetry occurs when a shape can be divided into two identical halves that are mirror images of each other.

What is point symmetry?

Back

Point symmetry occurs when every part of a shape has a matching part at an equal distance from a central point.
