It means that if two triangles have two sides with the lengths of the corresponding sides that are equal (congruent) and the angles between between the two sides congruent, then the triangles are congruent (i.e., the three corresponding lengths of sides and three corresponding angles are all congruent).
For example, if you know that triangle one has sides of length 1 and 2 and the angle between the two sides is 60 degrees and that triangle two has sides of length 1 and 2 and the angle between the two sides is 60 degrees, this theorem says that the triangles are congruent, so the length of third side of both triangles is the same and the measure of the other two angles in triangle one is the ame as the measure of the other two angles in triangle two.

Who is the father of congruence of triangles?
The father of congruence of triangles is Euclid, a renowned ancient Greek mathematician known as the "Father of Geometry." In his seminal work, "Elements," Euclid laid down the foundational principles of geometry, including the concept of congruence of triangles. He established the criteria for triangle congruence, such as the Side-Angle-Side (SAS) and Angle-Side-Angle (ASA) postulates, which are still fundamental in modern geometry. Euclid's contributions to the study of triangles and their congruence have had a lasting impact on mathematics and geometric reasoning.
What is SAS Congruence Theorem?
The side-angle-side congruence theorem states that if you know that the lengths of two sides of two triangles are congruent and also that the angle between those sides has the same measure in both triangles, then the two triangles are congruent.
What is Asa congruence postulate?
Angle side angle congruence postulate. The side has to be in the middle of the two angles
What is the type of congruence between the triangles shown?
side- angle- side

What are the four congruence postulates?
The postulates that involve congruence are the following :SSS (Side-Side-Side) Congruence Postulate - If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.SAS (Side-Angle-Side) Congruence Postulate - If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.ASA (Angle-Side-Angle) Congruence Postulate - If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.The two other congruence postulates are :AA (Angle-Angle) Similarity Postulate - If two angles of one triangle are congruent to two angles of another triangle, the triangles are similar.Corresponding Angles Postulate - If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
what- Fill in blank 1 and blank 2 to explain why Angle-Side-Angle Congruence helps imply Angle-Angle-Side Congruence?

What is triangle congruence theorem?
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
