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 are the congruence theorems or postulates?
They are theorems that specify the conditions that must be met for two triangles to be congruent.
Is a ASA triangle similarity postulate?
Not in the sense that you mean. With similarity postulates, such as SSS, the sides maintain a proportion with each other, and since there is only one side in ASA - there is nothing to compare it to? So this postulate reduces to: Is AA a similarity poostulate? which turns out to be true (given two angles, you can find the third).

What are the four congruence theorems for a right triangle?
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
What is reflexive symmetric and transitive properties of Congruence?
Congruence is basically the same as equality, just in a different form. Reflexive Property of Congruence: AB =~ AB Symmetric Property of Congruence: angle P =~ angle Q, then angle Q =~ angle P Transitive Property of Congruence: If A =~ B and B =~ C, then A =~ C
How the triangle similarity postulates are alike and how they differ from triangle congruence postulates?
Similarity is where triangles have equal angles at each corner. Congruence is where triangles have sides of equal length.
Wwhich of the following are not congruence theorems or postulates?

What do you called sss sas asa saa?
they are all postulates or shortcuts on finding 2 triangles congruence, except that SAA does not exist.
Are not congruence theorems or postulates?

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.
Who discovered the congruence of triangle?
The congruence of triangles is a fundamental concept in geometry, and it wasn't discovered by a single individual but rather developed over time through the work of various mathematicians. Ancient Greek mathematicians, particularly Euclid in his work "Elements," laid the groundwork for understanding triangle congruence through postulates and theorems. The criteria for triangle congruence, such as Side-Side-Side (SSS) and Angle-Side-Angle (ASA), were formalized later as geometry evolved.
