The two triangle congruence theorems are the AAS(Angle-Angle-Side) and HL(Hypotenuse-Leg) congruence theorems. The AAS congruence theorem states that if two angles and a nonincluded side in one triangle are congruent to two angles and a nonincluded side in another triangle, the two triangles are congruent. In the HL congruence theorem, if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, the two triangles are congruent.
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.
They are theorems that specify the conditions that must be met for two triangles to be congruent.
I am guessing you are interested in triangles. Here are two false triangle congruence theorem conjectures.1, If the angles of one triangle are equal respectively to the angles of another triangle, the triangles are congruent. ( abbreviated AAA).2. If two sides and one angle of a triangle are equal respectively the two sides and one angle of another triangle, the triangles are congruent. (abbreviated SSA)Comment: Draw triangles with pairs of equal sides but in which the included angle between the equal sides is acute in one case and obtuse in the others.
It is a special case of:the 3 sides (SSS) congruence, using Pythagoras,the 2 sides and included angle (SAS) congruence, using the sine rule.
There is nothing specific folloing right triangle congruence theorem. It depends on the order in whih the syllabus is taught.

there are 4 types of congruence theorem-: ASA,SSS,RHS,SAS
Congruence theorems are fundamental principles in geometry that establish when two triangles are congruent. The primary congruence theorems include 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. The Side-Angle-Side (SAS) theorem asserts that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent. Lastly, the Angle-Side-Angle (ASA) theorem states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.
the congruence theorems or postulates are: SAS AAS SSS ASA

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.
They are theorems that specify the conditions that must be met for two triangles to be congruent.

The only Two Triangle congruence shortcuts that do not prove congruence are: 1.AAA( Three pairs of angles in a triangle) & 2.ASS or SSA(If the angle is not in between the two sides like ASA.

Here are two false triangle congruence theorem conjectures.1, If the angles of one triangle are equal respectively to the angles of another triangle, the triangles are congruent. ( abbreviated AAA).2. If two sides and one angle of a triangle are equal respectively the two sides and one angle of another triangle, the triangles are congruent.

SSS, SAS, ASA, AAS, RHS. SSA can prove congruence if the angle in question is obtuse (if it's 90 degrees, then it's exactly equivalent to RHS).
The congruence theorems for right triangles are the Hypotenuse-Leg (HL) theorem and the Leg-Acute Angle (LA) theorem. The HL theorem states that if the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent. The LA theorem states that if one leg and one acute angle of one right triangle are congruent to one leg and one acute angle of another right triangle, then the triangles are congruent.
