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.
Any two angles of a triangle determine the third angle. As a result, the side angle angle theorem is equivalent to the angle side angle theorem.
AAA stands for angle-angle-angle SAS stands for side-angle-side and so forth
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.
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
The Congruent Triangle Theorem states that two triangles are congruent if their corresponding sides and angles are equal. There are several criteria for establishing congruence, including Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), and Hypotenuse-Leg (HL) for right triangles. This theorem is fundamental in geometry as it helps determine the equality of triangles based on their measurements. Congruent triangles have the same shape and size, allowing for various applications in proofs and problem-solving.
The La Congruence Theorem, often referred to in the context of triangle congruence criteria, includes several key examples such as the Side-Side-Side (SSS) theorem, which states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent. Another example is the Angle-Side-Angle (ASA) theorem, where two angles and the included side of one triangle are equal to the corresponding parts of another triangle, ensuring congruence. Additionally, the Side-Angle-Side (SAS) theorem asserts that if two sides and the included angle of one triangle are equal to those of another triangle, the triangles are congruent as well.
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)
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
To find the side lengths and hypotenuse of a right angle triangle.
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
