OL Wednesday 1/4- Transformations Introduction

Front

What is a geometric transformation?

Back

A geometric transformation is a function that moves or changes a shape in a specific way, such as translation, rotation, reflection, or dilation.

Front

What is translation in geometry?

Back

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

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a shape over a line (the line of reflection) to create a mirror image.

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape while maintaining its proportions, either enlarging or reducing it.

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

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

Back

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

Front

What is the center of rotation?

Back

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

Front

What is the difference between rotation and reflection?

Back

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

Front

What is an example of a real-world application of transformations?

Back

Transformations are used in computer graphics to manipulate images, such as rotating or resizing pictures.
