A right-angled triangle has a base of 5 cm, a height of 12 cm. Find the length of the hypotenuse.

Draw the triangle.Let the base = a, height = b and hypotenuse = ca = 5, b = 12, c = ?Using Pythagoras theorem, a 2 + b 2 = c 2 so, 5 2 + 12 2 = c 2 25 + 144 = c 2 169 = c 2 c = sqrt (169)c = 13So the hypoten...
