Congruence of triangles is like finding identical twins – but in the world of geometry! 
NCERT Solutions for Class 7 Maths Chapter 7 teaches students the concept of triangle congruence, where two triangles are said to be congruent if they have exactly the same shape and size. Sounds easy, right? But there’s more to it than meets the eye!
To determine whether two triangles are congruent, students learn about various congruence criteria. There’s the SSS (Side-Side-Side) criterion, where all three sides of one triangle are equal to the corresponding sides of another triangle. Imagine you’ve got two identical pieces of cake – you know they’re congruent because every slice is the same! 
Then there’s the SAS (Side-Angle-Side) criterion, where two sides and the included angle of one triangle match with another. It’s like making sure two triangles are in perfect alignment before declaring them twins. 
And don’t forget the ASA (Angle-Side-Angle) and RHS (Right Angle-Hypotenuse-Side) criteria – these make sure even the angles are on point!
The chapter explains all these criteria with plenty of examples and real-life applications, making it easier for students to grasp the concept. It even goes a step further and explains how congruence helps in solving real-world problems, like building structures or designing patterns in art.
Through practice exercises, students get to prove their skills by determining if triangles are congruent based on the criteria they’ve learned. By the end of the chapter, they’ll be confident in identifying congruent triangles, making geometry seem as easy as pie!
