Math 3 Unit 5 Test Review

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What are the properties of consecutive angles in a parallelogram?

Back

In a parallelogram, consecutive angles are supplementary, meaning they add up to 180 degrees.

Front

How can you determine if a statement about angles in a parallelogram is true or false?

Back

To determine if a statement is true or false, check if it aligns with the properties of parallelograms, such as the relationships between angles and sides.

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

If one angle of a parallelogram measures 70 degrees, what is the measure of the opposite angle?

Back

The opposite angle will also measure 70 degrees because opposite angles in a parallelogram are equal.

Front

What is the measure of the angles adjacent to a 70-degree angle in a parallelogram?

Back

The adjacent angles will each measure 110 degrees because they are supplementary to the 70-degree angle.

Front

What is the relationship between the diagonals of a parallelogram?

Back

The diagonals of a parallelogram bisect each other, meaning they cut each other in half.

Front

How do you find the measure of an angle in a triangle given two other angles?

Back

To find the measure of an angle in a triangle, subtract the sum of the two known angles from 180 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

In a triangle, if two angles are known to be 50 degrees and 60 degrees, what is the measure of the third angle?

Back

The third angle measures 70 degrees, calculated by subtracting the sum of the known angles from 180 degrees.
