Question

Which are measurements of the sides of a right triangle?

Answer 1

Let's try out the Pythagorean Theorem using this right triangle with sides of 5 and 12 cm, and a hypotenuse of 13 cm. We can verify that the Pythagorean Theorem is true by substituting in the values. The square root of 169 is 13, which is the measure of the hypotenuse in this

According to Pythagorean Theorem,
A right triangle's sides are equivalent to..

a² + b² = c²


Thus for a 3,4,5 right triangle

3² + 4² = 5²
9 + 16 = 25
25 = 25

Since this is true, these sides form a right triangle.
Hope this helps! :)
