Depends on the Triangle. Right triangles with a 90 degree angle: http://en.wikipedia.org/wiki/Pythagorean_theorem
If two sides of a triangle with a right angle are known, the Pythagorean Theorem can help you find the third one. It can also be used to verify whether a certain triangle is, indeed, a right triangle (if the three sides are known).
SAS Inequality Theorem the hinge theorem states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle.
A triangle with perpendicular legs is a right triangle, where one of its angles measures 90 degrees. The two legs of the triangle are the sides that form this right angle, while the third side, known as the hypotenuse, is opposite the right angle. In such triangles, the Pythagorean theorem can be applied, stating that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
It is not possible to determine the measure of an angle if the lengths of two sides are given.
The supplementary angle of the triangle.

We use the law of Cosines to be able to find : 1. The measure of the third side, when the measure of two sides and the included angle of a triangle ABC are known. 2. The measure of any angle, when the measure of the three sides of a triangle ABC are known.
The third wheel
Perimeter -2 known sides = 3rd side 180 -2 known angles = 3rd angle
The triangle is an isosceles triangle.
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
The hinge theorem in geometry states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle
