angled triangle is 7cm, find
its hypotenus​

Answer 1

Explanation:

(Draw a required diagram)

one side of isosceles right

angled triangle is (AB) 7cm

hence another side is also (BC) 7cm

hypotenuse(AC) =?

by using Pythagoras theorem,

(AC)²= (AB)²+(BC)²

(AC)²= (7)²+(7)²

AC²= 49+49

AC= √98

AC= √49×2

AC= 7√2
