It's a 3,4, 5  triangle so the sides are 6, 8, and 10

rational · Answer

how can we know its a 3,4,5 triangle ?

nikato · Answer

softball girl is right
You can always check using the long way

a^2 + b^2= c^2
6^2 + 8^2 = c^2
36+64= c^2
100= c^2 
Square root both sides
c=10

nikato · Answer

And you know 3,4,5
Because 6 and 8 can both be reduced by 2
So 3 and 4
And since your missing the longest side, hypotenuse, of the right triangle
So a 3,4,5 right triangle
