SAS (Side Angle Side) Congruence Criteria (Condition): When two sides and the included angle of one triangle is equal to the corresponding sides and the included angle of another triangle, the two triangles are congruent. Question 1. Under RHS rule, we consider only the hypotenuse and one corresponding side of the given two right triangles to prove the congruency of triangles. SSS Congruence Rule (Side – Side – Side) Two triangles are said to be congruent if all the sides of a triangle are equal to all the corresponding sides of another triangle. Aug 29, 2020 - ASA Congruence Rule Class 9 Video | EduRev is made by best teachers of Class 9. (The included side is the side between the vertices of the two angles.) It is called as AAS congruence rule when two triangles are congruent if any two pairs of angles and one pair of corresponding sides are equal. If any two angles and the included side are the same in both triangles, then the triangles are congruent. In the given figure ΔBAC = ΔQRP by SAS criterion of congruence. 3 3 4 1.

In ASA, since you know two sets of angles are congruent, you automatically know the third sets are also congruent since there are 180º in each triangle. Why SSA isn't a congruence postulate/criterion. This, condition of congruence is known as side-angle-side congruence. Image Coordinate Points-Step 2: Graph both triangles. Case 2: AB > DE The final congruence check for triangles. Again, in ∆OBA and ∆ODA, In congruency postulates, SSS, SAS, ASA, and AAS, three quantities are tested, whereas, in hypotenuse leg (HL) theorem, hypotenuse, and one leg are only considered, that too in case of a right triangle.
