A+B=C

that method is the way you find out if the triangle is a right triangle. you take the a + b-c and fill the numbers in.

if the to legs add up to the hypotenuse then you have a right triangle.

2. answer this missing side.

one leg equals = 12 which is A side

the other = 5

so we go c=a+b

c2=12+5

c2= (12x12) + (5x5)

c2= 144+25

c2=169( sqaure root it )

c=13

so the answer will be the c= 13 2

3.is the triangle a right triangle? prove it !!!

well one side equals 8 the other equals 6 so

a2+b2=c2

8+6=14

14 2=11 2

there for the triangle is not a right triangle.
