Congruence of Triangles - NCERT Class 7 Maths

This chapter begins with an introduction to Congruence of Triangles by explaining the basic concept of congruence among plane figures,line segments, angles and finally triangles.The congruence of triangles is the main topic of discussion and hence it is explained elaborately.Then the criteria for congruence of triangles such as SSS Congruence Criterion,SAS Congruence Criterion, ASA Congruence Criterion, are explained through SSS game, SAS game and ASA games respectively. Finally, congruence among right angled triangles i.e. RHS Congruence Criterion is explained in detail.
