A side of an hypotenuse isosceles right angled triangle is 7 cm. find its hypotenuse​

Answer»

Step-by-step explanation:

let the hypotenuse be 'x'

If the triangle is isosceles than the other side will be EQUAL too, i.e it will be 7cm

By PYTHAGORAS theorem,

(PERPENDICULAR)^2 + (base)^2 = (Hypotenuse)^2

(7)^2 + (7)^2 = x^2

49 + 49 = x^2

x^2 = 98

x = √98

x = 7√2 cm
