Do the following side lengths of a triangle, create a right triangle?If, so Why?
21, 28, 35

• No, not a right triangle

• Yes, because a²+b²>c²

• Yes, because a²+b²=c²

• Yes, because √a*b = x

Use the special right triangle properties to find g and f.

• g= 10 and f = 10√3

• g= 10√2 and f = 10√2

• g= 10√2 and f =10

• g= 10√3 and f =10
