Yes because the hypotenuse would be the longest side (13) and when squared equals 169. now when you square 5 and 12 (25 and 144) and add them, you get the 169, which is 13. so yes it’s a right triangle.
Triangle D is not a enlargement of Triangle A because it is not the same type of number. 3 is an odd number, while 60 is an even number. The answer is D.
