Question

The length of hypotonus of an isosceles right angled triangle is 10 cm then the length of equal sides is ----
10cm
5cm
10√2cm
5√2cm​

Answer 1

In an isosceles right-angled triangle two sides are equal.

If one side is 10cm then the other side is also 10cm

The hypotenuse is the biggest side

∴,(hypotenuse)² =10²+10²

⇒hypotenuse= $\sqrt{2 \times 100}$

$= 10 \sqrt{2}$
