SAS axiom is the rule which says that if the two sides of a triangle are equal to the two sides of another triangle, and the angle formed by these sides in the two triangles are equal, then these two triangles are congruent by the SAS criterion.
What is a SAS Triangle?Ī triangle whose two sides and the angle formed by them is known as a SAS triangle. If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are said to be congruent by the SAS congruence rule.

If the two sides and the angle formed at their vertex of one triangle are equal to the two corresponding sides and the angle formed at their vertex of another triangle then the triangles are congruent by SAS Criterion for Congruence.We represent the congruence of triangles using the symbol (≅).Two triangles are said to be congruent if their shape and size are exactly the same.Then to calculate the value of ∠A use the sum of interior angles of a triangle is 180° Now apply the sine rule in the triangle ABC and calculate the value of ∠C. The low of cosine gives the formula b 2 = a 2 + c 2 − 2ac cos B, where AB = c BC = a and AC = b.
Now, to find the value of side AC, we will use the law of cosine. The SAS Criterion stands for the 'Side-Angle-Side' triangle congruence theorem. Under this criterion, if the two sides of a triangle are equal to the two sides of another triangle, and the angle formed by these sides in the two triangles are equal, then these two triangles are congruent. Thus, we can conclude that the corresponding parts of the congruent triangles are equal. ED falls on PQ, EF falls on QR, and DF falls on PR. This means D falls on P, E falls on Q, and F falls on R. We can represent this in a mathematical form using the congruent triangles symbol (≅). They can be considered as congruent triangle examples. Thus, we can say that these are congruent. These two triangles are of the same size and shape. Let's discuss the SAS congruence of triangles in detail to understand the meaning of SAS. SAS congruence is the term which is also known as Side Angle Side congruence, which is used to describe the relation of two figures that are congruent.
