Unit 3 Review--Final Exam

Front

What is the scale factor of the dilation that takes quadrilateral P to quadrilateral Q if they are similar?

Back

5/4 or 1.25

Front

What is the scale factor of the dilation that takes quadrilateral Q to quadrilateral P if they are similar?

Back

4/5 or 0.8 or .8

Front

Define similarity in geometry.

Back

If there is a sequence of rigid transformations and dilations that take one figure to the other, then they are similar.

Front

What is the measure of angle A'B'C if the options are 20°, 40°, 60°, and 80°?

Back

40°

Front

Solve for X if the options are 2 ft, 3 ft, 4 ft, and 6 ft.

Back

2 ft

Front

What is a quadrilateral?

Back

A four-sided polygon.

Front

What are the properties of similar figures?

Back

Similar figures have the same shape but not necessarily the same size; corresponding angles are equal and corresponding sides are proportional.

Front

What is a dilation in geometry?

Back

A transformation that alters the size of a figure but not its shape.

Front

What is the formula for finding the scale factor of a dilation?

Back

Scale factor = (length of side in image) / (length of corresponding side in pre-image).

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.
