Transformations

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 four main types of transformations?

Back

Translation, Reflection, Rotation, Dilation.

Front

What does translation mean in geometry?

Back

Translation means to slide a shape from one position to another without turning it.

Front

What does reflection mean in geometry?

Back

Reflection means to flip a shape over a line to create a mirror image.

Front

What does rotation mean in geometry?

Back

Rotation means to turn a shape around a fixed point.

Front

What is dilation in geometry?

Back

Dilation means to enlarge or reduce a shape while keeping its proportions.

Front

What is the x-axis?

Back

The x-axis is the horizontal line in a coordinate plane.

Front

What is the y-axis?

Back

The y-axis is the vertical line in a coordinate plane.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0,0).

Front

How do you identify a translation on a graph?

Back

A translation can be identified by a shape that has moved to a new location without changing its size or orientation.
