Dilations and Sequences

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the four main types of transformations?

Back

Reflection, Rotation, Translation, Dilation.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape.

Front

What does the term 'scale factor' mean?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a figure during a dilation.

Front

If a scale factor is greater than 1, what happens to the figure?

Back

The figure enlarges.

Front

If a scale factor is less than 1, what happens to the figure?

Back

The figure reduces in size.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but different sizes.

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are the same shape and size, while similar figures are the same shape but not necessarily the same 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.
