G9-MATH-L8 QUADRILATERALS

What is a parallelogram?

• A quadrilateral with one pair of parallel sides
• A quadrilateral with two pairs of opposite sides parallel
• A quadrilateral with all sides equal
• A quadrilateral with no parallel sides

What happens when you cut a parallelogram along one of its diagonals?

• You get two congruent triangles
• You get two different triangles
• You get a rectangle
• You get a square

In a parallelogram, which of the following statements is true?

• Opposite sides are unequal
• Opposite angles are equal
• Adjacent angles are equal
• All sides are equal

If a quadrilateral has opposite sides that are equal, what can be concluded?

• It is a rectangle
• It is a rhombus
• It is a parallelogram
• It is a trapezoid

What is the relationship between the diagonals of a parallelogram?

• They are equal and bisect each other
• They are unequal and do not bisect each other
• They bisect each other but are not equal
• They are perpendicular to each other

Which theorem states that the diagonals of a parallelogram bisect each other?

• Theorem 8.2
• Theorem 8.4
• Theorem 8.6
• Theorem 8.9

If in a quadrilateral, each pair of opposite angles is equal, what can be concluded?

• It is a rectangle
• It is a rhombus
• It is a parallelogram
• It is a square

What is the converse of Theorem 8.2?

• If a quadrilateral is a parallelogram, then opposite angles are equal
• If a quadrilateral has equal opposite sides, then it is a parallelogram
• If a quadrilateral has equal diagonals, then it is a rectangle
• If a quadrilateral has equal adjacent sides, then it is a rhombus

In a parallelogram, what can be said about the angles formed by the intersection of the diagonals?

• They are all right angles
• They are equal
• They are supplementary
• They are complementary

What property do the diagonals of a rectangle have?

• They bisect each other and are equal
• They bisect each other but are not equal
• They are equal but do not bisect each other
• They are perpendicular to each other
