Ch 5 Review of Transformations

Front

What is a transformation in geometry?

Back

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

Front

What are the four main types of transformations?

Back

Translation, Reflection, Rotation, and Dilation.

Front

What is translation in geometry?

Back

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

Front

What is reflection in geometry?

Back

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

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape 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 shape but keeps its proportions the same.

Front

What does it mean when a shape is enlarged?

Back

Enlargement occurs when the scale factor of a dilation is greater than one, making the shape larger.

Front

What does it mean when a shape is reduced?

Back

Reduction occurs when the scale factor of a dilation is less than one, making the shape smaller.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that describes how much a shape is enlarged or reduced during dilation.

Front

What is the X-axis?

Back

The X-axis is the horizontal line in a coordinate plane where the Y-coordinate is zero.
