Question

The length of the hypoteneuse XZ of an isosceles right angled triangle XYZ, where XY is 5 cm is ...

​

Answer 1

AnsweR

It is given that isosceles right angled triangle .

So in that two sides must be equal.

They are 5 and 5 cm respectively.

Now third side hypotenuse will be ' x '

Apply Pythagoras theorem for finding x.

⇒ x² = 5² + 5²

⇒ x² = 50

⇒ x = 5√2 cm

So the hypotenuse is 5√2 cm.
