Question

1. Find the hypotenuse of a right-angled triangle with base 8cm and height 6cm​

Answer 1

Answer:

H² = 8² + 6²

     = 100

∴ H = 10 cm

Answer 2

Answer:

Let the third side(hypotenuse) be x

Using Pythagoras theorem,

(8)²+(6)²=x²

64+36=x²

100=x²

10=x

Therefore the length of the third side is 10 cm.

U can use this shortcut

(3,4,5) is a Pythagorean triplet

Multiply 2 to it

So (6,8,10) is a also a Pythagorean triplet,

Which means the third side
