The two sides correspond to equal, and the corresponding angles of the clamp are equal, then the beam triangle is congruent, that is, SAS
If the three sides are equal, then the two triangles are congruent, i.e., SSS
If two angles are equal and one edge is equal, then there is congruent AAS, and one is ASA

1. Three groups of two triangles with equal sides (SSS or "edge-edge-edge") also explains the reason for the stability of triangles. 2 There are two triangles with equal sides and their angles corresponding to congruence (SAS or "corner edges"). 3.

4. There are two angles and the opposite side of one of the corners correspond to two equal triangle congruence (AAS or "corner corner") 5. The conditions for the congruence of a right triangle are: the hypotenuse and the right angle side of a Yu Sen correspond to the equal congruence of two right triangles (hl or "hypotenuse, right angled side") Therefore, the mean kernel destruction difference of SS, SAS, ASA, AAS, HL is the theorem for determining the congruence of triangles.

Determination of the congruent three-skin blue ball horn:1) SSS (edge edge edge): The triangle corresponding to the three burning orange sides is congruent triangles.
2) SAS (Corner Edge): The triangle corresponding to the two sides and their angles is congruent triangle.
3) ASA (Corner Corner): The two corners and their edges correspond to the congruence of the triangle.
4) AAS (Corner Edge): Two corners and the opposite side of one of the corners correspond to equal triangle congruence.
5) RHS (Right Angle, Hypotenuse, Edge) (also known as HL theorem (Hypotenuse, Right Angle)): In a pair of right triangles, the hypotenuse and the other right angle are equal.
Properties: 1. The corresponding angles of congruent triangles are equal.

The corresponding sides and corresponding angles of the congruent triangle are equal. Similarly, if two triangles are edged, the two triangles with three corresponding sides equal are congruent triangles.
On the corner edge, two triangles with equal opposite sides and one corresponding angle are congruent triangles (must be the angles between the two sides).
Angular edges, two triangles with equal corresponding angles and one opposite side equal are congruent triangles.
All three corners are 60 degrees.
Corner corners, two triangles with equal corresponding angles and one equal pair of opposite sides are congruent triangles (as distinguished from the above, here refers to the sides sandwiched by two corresponding angles.) The above is not).
The hypotenuse and right-angled edges, a straight-and-a-he, annihilated corner-edge, and a hypotenuse corresponding to the same (only applicable to the sides and angles of the right-angled triangle correspond to the same respectively, then the two triangles are congruent!).

SSS, SAS, ASA, AAS, HL are all theorems for determining triangles, all-core ants, etc.
Note: There is no AAA (corner angle) and SSA (edge corner) in the congruence judgment (exception: the right triangle is changed to HL, which belongs to SSA), neither of which can uniquely determine the shape of the triangle.
