Question

Which best explains whether a triangle with side lengths 5cm , 13cm and 12 cm is a right triangle the triangle is a right

Answer 1

A: The triangle is a right triangle because 5 (to the 2nd power) + 12 (to the second power) = 13 (to the second power)

Explanation:

25 + 144 = 169

169 = 169

To determine if it is a right angle, take all three numbers and multiply them by the second power. After you get all the numbers in their second power form, look at the first two numbers. If they equal the same as the third number, that is a right angle.

Answer 2

Right triangle.

Explanation:

We are asked to determine whether the given side lengths are sides of a right triangle or not.

We know that side lengths of a right triangle are Pythagoras triplets. The square of the longest must be equal to sum of squares of other sides.

Let us check sides of our given triangle.

`13^2=5^2+12^2`

`169=25+144`

`169=169`

Since both sides of equation are equal, therefore, the given side lengths are sides of a right triangle.
