Identify Transformations

Front

Can a shape undergo multiple transformations? Give an example.

Back

Yes, a shape can undergo multiple transformations. For example, a shape can be reflected over the y-axis and then translated 3 units up.

Front

Define reflection in geometry.

Back

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

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 is a rotation of 180 degrees?

Back

A rotation of 180 degrees turns a shape around a point to face the opposite direction.

Front

What is the difference between a rotation and a reflection?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that moves a shape to a different location without changing its size or orientation.

Front

What does it mean to dilate a shape?

Back

Dilation is a transformation that enlarges or reduces a shape by a scale factor, while maintaining its proportions.

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 is the center of rotation?

Back

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

Front

What is a scale factor in dilation?

Back

The scale factor is the ratio of the size of the new shape to the size of the original shape in a dilation.
