Quadrilaterals

What is the Trapezoid Midsegment Theorem?

• The midsegment of a trapezoid is parallel to the bases and half the sum of the bases.

• The midsegment of a trapezoid is equal to the height of the trapezoid.

• The midsegment of a trapezoid is perpendicular to the bases.

• The midsegment of a trapezoid is equal to the length of the longer base.

Which property is NOT a property of a parallelogram?

• Opposite sides are parallel.

• Opposite sides are congruent.

• Opposite angles are congruent.

• All angles are right angles.

What is necessary to prove a quadrilateral is a parallelogram?

• One pair of opposite sides is parallel and congruent.

• All sides are congruent.

• The diagonals bisect each other.

Which of the following is a property of a rectangle (a special type of parallelogram)?

• Diagonals are congruent.

• All angles are acute.

• Opposite sides are not congruent.

What does the Trapezoid Midsegment Theorem state about the length of the midsegment compared to the bases?

• It is the average of the lengths of the bases.

• It is twice the length of the shorter base.

• It is half the sum of the lengths of the bases.

• It is equal to the length of the longer base.

Which statement is true for all parallelograms?

• Diagonals are perpendicular.

• Diagonals bisect each other.

• All sides are congruent.

How can you prove a quadrilateral is a parallelogram using its diagonals?

• Show that the diagonals are congruent.

• Show that the diagonals bisect each other.

• Show that the diagonals are perpendicular.

• Show that one diagonal is twice as long as the other.

What is a unique property of a rhombus (a special type of parallelogram)?

• All sides are congruent.

• Diagonals are congruent.

• All angles are right angles.

• Only one pair of opposite sides is parallel.

Which of the following is NOT a property of a square (a special type of parallelogram)?

• All sides are congruent.

• All angles are right angles.

• Diagonals bisect the angles.

• Diagonals are not congruent.

In a parallelogram, if one angle is right, what can we conclude about the parallelogram?

• It is a rectangle.

• It is a rhombus.

• It is a square.

• It cannot be determined.
