For these questions we will either be doing the formula
a2+b2=c2 or
c2-b2=a2
1.) we are trying to find the unknown hypotenuse.
1 2+2 2 = 5 2
Then we take the square root of 5 which is 2.2
To identify a triple you basically write out the formula and solve to make sure they are even.
So this one isn’t a triple because all the side ain’t even
2.) 10 2- 8 2 = 36 2
Then take the square root and it equals 6 and this is a triple triangle because when you go six squared with 8 squared you get 100 and the square root of that is 10.
And that’s all the basics feel free to look at the uploaded picture.
I can do the others later if you want o have to get to school.
