Answer:
1- longest side
2- adjacent and opposite
3-a^2 + b^2 = c^2
4- yes, by using pythagorean theorem
Step-by-step explanation:
1- the hypotenuse is always the longest side
2- the three sides are called hypotenuse, adjacent and opposite
3- a^2 + b^2 = c^2 is a formula to solve for missing legs
4- pythagorean theorem (a^2 + b^2 = c^2) is the formula to solve for missing legs/hypotenuse . A and B represents a leg and c will always be the hypotenuse, you then isolate for the letter you are missing
