Question

The right-angled triangle with sides a = 1 cm, b = 2 cm and hypotenuse c = 3 cm satisfies Pythagoras theorem.

• A. True
• B. False

Answer 1

The correct option is B False

As per the Pythagoras theorem $c^2=a^2+b^2$ where a and b are sides, c is the hypotenuse
$c=\sqrt{a^2+b^2}$
substituting in 1 we get,
$c^2=1^2+2^2$
$c^2=5$
$c=\sqrt{5}$
But here, c is given as 3 cm hence the given right-angled triangle is not satisfying pythagoras theorem
Hence, it is False
