SAS congruence

भुजा-कोण-भुजा सर्वांगसमता

In this Class 9 Mathematics topic from the chapter Triangles, students learn the SAS (Side–Angle–Side) congruence criterion. They understand that two triangles are congruent when two corresponding sides and the angle included between them are equal. The topic develops skills for identifying corresponding parts, matching vertices correctly, presenting clear geometric proofs, and using SAS to establish that other corresponding sides and angles are equal in congruent triangles.
