If you know all the side lengths then you can use the Pythagorean Theorem. The theorem states that a^2+b^2=c^2 when c=the hypotenuse or the side opposite the suspected right angle. So multiply the two shorter sides by themselves (a*a+b*b) and then add them together. Finally, take the square root of this number and if it equals the length of the hypotenuse then the triangle is right. A triangle with the side lengths 3,4, and 5 or multiples of that (i.e. 9, 16, and 25) are right triangles.

How do you prove a right angle triangle?
You cannot prove "a right angle triangle". You may or may not be able to prove statements about right angled triangles but that will depend on the particular statement.
Does pythagorean theorem prove a triangle to be a right triangle?
Yes
How to prove an isosceles triangle with one angle bisector?
What have we got to prove? Whether we have to prove a triangle as an Isoseles triangle or prove a property of an isoseles triangle. Hey, do u go to ALHS, i had that same problem on my test today. Greenehornet15@yahoo.com
Could 3 5 and 7 represent the length of the sides of a right triangle?
no it cannot represent as in angle triangle rule it doesnt prove that term
What type of triangle proves the pythagorean theorerm?
The Pythagorean Theorem applies only to right triangles. (But they don't prove it.)
