triangle....?

how do you determine if a triangle is a right triangle if they just give you the side lengths of each side?

1. If a^2 + b^2 = c^2 with a > b > c then it is a right triangle.
2. you can take the square root of the sum of the square two shorter sides (if the sides are a, b, and c, where c is the longer side, c = sqrt(a^2 + b^2) ), if it is equal to the third side, it is a right triangle. (Pythagoreans Theorem)
3. if the sum of the squaresf two sides is equal to the square of the third, it is a right angled triangle.,otherwise not.
4. our good friend pythagorus will help us out here. if the square of the alrgest side is equal to the sum of the squares of the other two sides then it is a right triangle. c^2 = a^2 + b^2 this will be true for any right triangle.
5. A right triangle will always form the factors for the Pythagorean theorem - a^2 + b^2 = c^2 a= leg a b= leg b c= hypotenuse If the number fit into this equation (c will always be the largest number) then the triangle is a right triangle. For example if you have a triangle with sides of 3, 4, and 5 3^2 + 4^2 = 5^2 9+16=25 25 = 25
6. If you can make a square in one of the corners of the triangle or if the measurement is 90 degrees.And another way is by using the pythagoream theorom.a2+b2=c2
7. well all u have to do is determine if it has a right angle. if a length is like 6 ft height and then they give base 15 and 13 then what u do is the height is smaller then the bases but that also leaves u with a scalene but then one side would be much longer there u go.
8. USE THE PERTHAGREAN THEROM(im not sure on the spelling).Asquared +bsquared=csquared
9. try using tan(opp/hyp),cos(adj/hyp),or, sin(opp/hyp) to find the angle lengths. once you find two add them and subtract from 180. if u get an error the angle is a right.
