Answer:
Triangle A:
Side A is 4 and side B is 2, Side C will =6
because in a right angle the hypotenuse or the longest side will always appear directly across from the right angle. and side A and B will always make up a right angle according to the pythagorean theorem to determine a right triangle.
Triangle B:
Side A is 5 and side B is 2, Side C is the square root of 45 or 6.71
because in a triangle the hypotenuse or longest side will alway be across from the two shorter angles. Using the pythagorean theorem to determine if a triangle is a right angle we would do A + B = C. In this case triangle B is not a right angle.
I hope this helps you :)
