Let the two right sides of a right triangle be a. B and the length of the hypotenuse be c. if the height of the hypotenuse is h, then what is the shape of the triangle with H, C plus h and a plus B as sides
isosceles right triangle
If the two right sides of a right triangle are 5 and 12 respectively, the height of the hypotenuse is ()
A. 125B. 512C. 6013D. 1360
The length of hypotenuse is 52 + 122 = 13, 2S △ = 5 × 12 = 13h, H = 6013, so C
