Transformations Introduction

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

Define translation in geometry.

Back

Translation is a transformation that slides a figure from one position to another without turning it.

Front

What is reflection in geometry?

Back

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

Front

Explain rotation in geometry.

Back

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

Identify the line of reflection.

Back

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

Front

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

Back

To rotate a figure 90 degrees clockwise means to turn the figure 90 degrees to the right around a fixed point.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

How do you identify a translation?

Back

A translation can be identified by the same shape appearing in a different location without any rotation or reflection.

Front

What is the effect of dilation on a shape?

Back

Dilation enlarges or reduces a shape while maintaining its proportions.
