Sample Questions

1multiple correct

Which of the following properties are true for a parallelogram? (Select all correct answers)

Show answer

Opposite sides are equal, Opposite angles are equal, Diagonals bisect each other

A parallelogram has three main properties: opposite sides are equal (Theorem 8.2), opposite angles are equal (Theorem 8.4), and diagonals bisect each other (Theorem 8.6). Not all parallelograms have 90-degree angles or equal sides.

2true false

If in a quadrilateral, each pair of opposite sides is equal, then it is a parallelogram.

Show answer

True

This statement is Theorem 8.3, which is the converse of Theorem 8.2. If each pair of opposite sides of a quadrilateral is equal, then it is indeed a parallelogram.

3multiple choice

In parallelogram PQRS, if angle P = 70°, what is the measure of angle R?

Show answer

70°

According to Theorem 8.4, in a parallelogram, opposite angles are equal. Since P and R are opposite angles, angle R = angle P = 70°.

4multiple choice

Where do the diagonals of a parallelogram intersect?

Show answer

At their midpoints

According to Theorem 8.6, the diagonals of a parallelogram bisect each other. This means they intersect at their midpoints, dividing each diagonal into two equal parts.
