Question

Two of the sides of a right angled triangle are 5m nd 12m.find the length of the third side(there are two possible answers)

Answer 1

the 5-12-13 right triangle is one of the most commonly used ones.

So, you have a 5m-12m-13m triangle.

Or, you may have one with sides

5m,√119 m,12m

but usually the hypotenuse is not called one of the "sides" in a right triangle.
