Given an isosceles trapezoid, BK height, AK = 6cm. КD = 11 cm. Find the middle line of the trapezoid.

The height of an isosceles trapezoid, drawn from the top of an obtuse angle, divides the larger base into two segments, the smaller of which is equal to the half-difference of the bases, and the larger half-sum. Then the segment KD is equal in magnitude to the middle line of the trapezoid.

MP = KD = 11 cm.

Answer: The middle line of the trapezoid is 11 cm.
