Grade 8 Transformations Practice 2024

Front

What are congruent geometric figures?

Back

Congruent geometric figures have the same size and same shape.

Front

What does it mean for two figures to be similar?

Back

Similar figures have the same shape but not necessarily the same size.

Front

What is the scale factor in dilation?

Back

The scale factor is a number that scales, or multiplies, the dimensions of a figure.

Front

If Point A is at (-2,-2) and is dilated by a scale factor of 2, what are the new coordinates?

Back

The new coordinates are (-4,-4).

Front

If Point B is at (0,4) and is dilated by a scale factor of 3, what are the new coordinates?

Back

The new coordinates are (0,12).

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in size and shape, while similar figures have the same shape but different sizes.

Front

How do you determine if two figures are congruent?

Back

Two figures are congruent if you can overlay one on the other perfectly.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape.

Front

What does it mean to solve for X in an equation?

Back

To solve for X means to find the value of X that makes the equation true.

Front

If two angles are equal, what can be said about the figures they belong to?

Back

If two angles are equal, the figures may be similar or congruent, depending on other factors.
