Trapezoid Properties Quiz

What is the formula for the median of a trapezoid?

• The median is equal to twice the sum of the bases.

• The median is equal to half the sum of the bases.

• The median is equal to the difference of the bases.

• The median is equal to the sum of the bases.

In a trapezoid, if the median is given as negative x plus 21, and the bases are 11 and 17, what is the value of x?

• x = -7

• x = 21

• x = 14

• x = 7

How do you solve for x when given the median and bases of a trapezoid?

• Add the bases and divide by 2, then set equal to the median.

• Subtract the bases and multiply by 2, then set equal to the median.

• Multiply the bases and divide by 2, then set equal to the median.

• Add the bases and multiply by 2, then set equal to the median.

What is the relationship between consecutive interior angles in a trapezoid?

• They are congruent.

• They are supplementary.

• They are complementary.

• They are equal.

If angle A is 11x + 8 and angle B is 95 in a trapezoid, what is the value of x?

• x = 7

• x = 9

• x = 5

• x = 11

In an isosceles trapezoid, if angle Q is 28x - 11 and angle R is 51, what is the value of x?

• x = 4

• x = 5

• x = 3

• x = 6

How do you find the measure of an angle in an isosceles trapezoid?

• Use the difference of the bases.

• Use the sum of the bases.

• Use the congruence of opposite angles.

• Use the supplementary property of consecutive angles.

What is the formula to find the length of a base in a trapezoid using the median?

• Base length = median - half the other base.

• Base length = median + half the other base.

• Base length = 2 times the median minus the other base.

• Base length = 2 times the median plus the other base.

If the median of a trapezoid is 7x - 4 and the bases are 38 and 6x - 6, what is the value of x?

• x = 7

• x = 6

• x = 5

• x = 4

In a trapezoid, if the base length is given by 6x - 6 and x is found to be 5, what is the length of the base?

• 27

• 26

• 25

• 24
