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

What are the three main types of transformations?

Back

The three main types of transformations are translation, rotation, and reflection.

Front

Define translation in geometry.

Back

Translation is a transformation that slides a shape from one position to another without turning or flipping 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 point?

Back

A translation adds a specific value to the x and y coordinates of a point.

Front

What is the center of rotation?

Back

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

Front

What is the line of reflection?

Back

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

Front

How do you identify a rotation transformation?

Back

A rotation transformation can be identified by the angle of rotation and the direction (clockwise or counterclockwise).
