It is no more nor less important than any other theorem for congruence.

An example is Pythagoras's Theorem: that the sum of the squares of the two shorter side lengths of a triangle with a right-angle is equal to the square of the length of the side opposite the right angle.
the Pythagorean theorem is the following:a2 + b2 = c2So for example:then you will solve for whatever side you are searching forbut for this theorem to work it must be a right triangle! and "c" must be the side across from the right angle
There are three main ways to prove to triangles congruent. If all the sides match, if a side then an included angle and the next side and last angle-side angle. SSS, SAS. ASA
AAA stands for angle-angle-angle SAS stands for side-angle-side and so forth

180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
You need SAS (side angle side), SSS (side side side), ASA (angle side angle), AAS (angle angle side) or CPCTC (corresponding parts of congruent angles are congruent)
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent.

To find the side lengths and hypotenuse of a right angle triangle.

If the 2 sides of a right angle triangle are known then the 3rd side can be found by using Pythagoras' theorem.
In a triangle, if one side is longer than the other side, the angle opposite the longer side is the larger angle. It state that If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.. I hope it will help in your study..... AJ
