1. The midsegment of a trapezoid connects the   of the non-parallel sides.

2. The midsegment of a trapezoid is   to the bases.

3. The length of the midsegment of a trapezoid is equal to   of the sum of the lengths of the bases.

4. In trapezoid ABCD, AB is parallel to CD. If AB = 10 units and CD = 16 units, what is the length of the midsegment?

ABCD1016

5. A trapezoid has bases measuring 7 cm and 13 cm. Calculate the length of its midsegment.

6. If the midsegment of a trapezoid is 12 inches long and one base is 8 inches long, what is the length of the other base?

a

4 inches

b

16 inches

c

10 inches

d

20 inches

7. The midsegment of a trapezoid is represented by the expression 3x - 2. The bases of the trapezoid are 2x + 1 and 4x - 5. Find the value of x and the length of the midsegment.

8. In trapezoid PQRS, M is the midpoint of PS and N is the midpoint of QR. If PQ = 5y + 7, SR = 3y + 3, and MN = 15, find the value of y.

PQRSMN5y + 73y + 315
