A2+B2=C2
A and B are the sides of a right triangle that aren't directly across the right angle. C is the hypotenuse. (This only applies to right triangles).
Also, one that does pertain to all triangles is the well-known Law of Cosines, one used to develop the Pythagorean Theorem:
c2 = a2 + b2 - abcos(A), where "c" is the hypotenuse, "b" is one side, "a" is another, and "A" is the angle on the opposite's side. (Between the opposite and the adjacent).
It is a scalene triangle that has three different lengths and no angles are equal in size.
A SCALENE triangle has all three sides different lengths.
its not fair!
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.

-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
All three sides have different lengths.
Yes, the triangle is right-angled because 322 + 602 = 682. Given all three side lengths, you can use the Pythagorean relationship to determine whether a triangle is or is not right-angled. The right angle would be opposite the hypotenuse, 68.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.

A triangle in which lengths of the three sides are different is called a scalene triangle.
A triangle with a right angle and different lengths for sides is a right, scalene triangle.
