The height of the isosceles traction eaten from the vertex C divides the base AD into lengths 1 and 5 find the length of the base BC.

Let us draw from the vertex C the second height of the CК. Since the trapezoid is isosceles, the height of the ВН and СK cuts off on the larger base of the AD are equal to the segments AH = KD = 1 cm.Then AD = AН + НD = 1 + 5 = 6 cm. and СK – heights perpendicular to the blood pressure, then BC = НК = AD – AН – DC = 6 – 1 – 1 = 4 cm.
Answer: The length of the base of the BC is 4 cm.
