Transformations and similarities quick check

Math 8

1 answer

Here are a few quick check questions on transformations and similarities for Math 8:

1. What is a reflection in math?

A reflection is a transformation that "flips" a figure over a line, creating a mirror image of the original figure.

2. What is a translation in math?

A translation is a transformation that slides a figure from one location to another without changing its shape or orientation.

3. What is a rotation in math?

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

4. What is a dilation in math?

A dilation is a transformation that changes the size of a figure without changing its shape. It can either enlarge or reduce the figure.

5. What is a similarity in math?

Two figures are similar if their corresponding angles are congruent and their corresponding sides are in proportion.

Remember to always use appropriate notation (such as prime notation) to indicate the image or pre-image of a figure after a transformation.
