Question

The length of each leg of an isosceles right triangle is 3cm, what is the length of the hypotenuse? Please help very confusing.

Answer 1

Answer: The length of the hypotenuse is 3√2 cm.

Explanation:

An isosceles triangle is a triangle with at two congruent sides. We know two side lengths (3 and 3), and since the triangle is a right triangle, we can use Pythagorean Theorem to find the hypotenuse.

3² + 3² = c²

9 + 9 = c²

18 = c²

take the square root of both sides and you will get

c = 3√2
