ASA congruence

ASA सर्वांगसमता नियम

In this Class 9 Mathematics topic from the chapter Triangles, students learn the ASA (Angle-Side-Angle) congruence criterion. They understand that two triangles are congruent when two corresponding angles and the side included between those angles are equal. The topic develops skills for identifying corresponding parts, matching vertices in the correct order, writing a valid congruence statement, and using ASA to justify geometric results and solve problems involving triangles.
