We describe a circle around a right-angled triangle ABC with a center at point O.
The inscribed angle ACB = 90 and rests on the arc AB, then the degree measure of the arc AB = 180, and therefore the hypotenuse AB is the diameter of the circumscribed circle.
Then ОА = ОВ = R = AB / 2 = 14/2 = 7 cm.
The median OС is the radius of the circumscribed circle, then OС = OA = OB = 7 cm.
Answer: The median length is 7 cm.
