Question

State if each triangle is a right triangle.

Answer 1

Yes.

Explanation:

To find if a triangle is a right triangle or not, we use the Pythagorean theorem. The Pythagorean theorem states that
`a^(2) + b^(2) = c^(2)`.

a and b are the triangle legs. The c is the hypotenuse of the triangle.

Now, to find if a triangle is a right triangle, we plug in 9 for a and b and 9root2 for c.

`9^(2) + 9^(2) = (9√(2))^(2)`

81 + 81 = 81 * 2

162 = 162

So the given triangle, is indeed a right triangle.
