8th math Transformations

Front

What is a dilation in geometry?

Back

A dilation is a transformation that produces a similar figure by enlarging or reducing it based on a scale factor.

Front

What does rotation mean in the context of transformations?

Back

Rotation means to turn a figure around a fixed point.

Front

What is the term for a transformation that enlarges an image?

Back

Dilation.

Front

What are the three basic types of transformations in geometry?

Back

The three basic types of transformations are translation (slide), rotation (turn), and reflection (flip).

Front

What is the point that is transformed called?

Back

The point that is transformed is called the Pre-Image.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the difference between a translation and a rotation?

Back

A translation slides a figure to a new position without changing its shape or orientation, while a rotation turns a figure around a fixed point.

Front

What is the scale factor in a dilation?

Back

The scale factor is the ratio of the length of a side of the image to the length of the corresponding side of the pre-image.

Front

How do you determine if two figures are similar?

Back

Two figures are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is the center of rotation?

Back

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