Side-Angle-Side Postulate (SAS postulate) If all three sides of a triangle are congruent to corresponding three sides of other triangle then the two triangles are congruent.Īngle-Side-Angle Postulate (ASA postulate)Īccording to this postulate the two triangles are said to be congruent if two angles and the side between these two angles of one triangle are congruent to corresponding angles and the included side (side between two angles) of the other triangle. If the hypotenuse and one of the legs (sides) of a right triangle are congruent to hypotenuse and corresponding leg of the other right triangle, the two triangles are said to be congruent.
There are two theorems and three postulates that are used to identify congruent triangles.Īs per this theorem the two triangles are congruent if two angles and a side not between these two angles of one triangle are congruent to two corresponding angles and the corresponding side not between the angles of the other triangle. When triangles are congruent corresponding sides (sides in same position) and corresponding angles (angles in same position) are congruent (equal). Two triangles are said to be congruent if they have same shape and same size.
