Kendall Hunt Geometry Unit 3 Review

Front

If a figure is dilated, corresponding __________ are congruent.

Back

Angles

Front

If a line divides two sides of a triangle proportionally, the line must be ___________ to the third side of the triangle.

Back

parallel

Front

Is line BC parallel to DE? Choose the best justification.

Back

Line BC is not parallel to line DE because there is no dilation that sends triangle ADE to triangle ABC.

Front

In triangle ABC, the measure of angle A is 90 degrees. The length of AB is 1 unit. The length of AC is 8 units. Find the approximate length of BC.

Back

BC = 8.1 units

Front

These rectangles are...

Back

Not similar

Front

What is the definition of dilation in geometry?

Back

A transformation that produces an image that is the same shape as the original, but is a different size.

Front

What is the Triangle Proportionality Theorem?

Back

If a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

Front

What is the Pythagorean Theorem?

Back

In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the scale factor in a dilation?

Back

The ratio of the length of a side of the image to the length of the corresponding side of the original figure.
