Question

5 cm and 12 cm can be two sides of a right-angled triangle. State true or false.

• A. True
• B. False

Answer 1

The correct option is A

True

Right angled triangles satisfy Pythagoras theorem. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Sides of lengths 5 cm, 12 cm and 13 cm form sides of a right-angled triangle.
$5^2+{12}^2={13}^2$
