Question

Which side lengths form a right triangle? please help

Answer 1

In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides.

Answer 2

you should square each of the smaller numbers and add them together. after that square the bigger number. if the results gotten is equivalent, it is a right angled triangle. feel free to clarify. I used pythagoras theorem to solve this btw
