NCERT Solutions Class 7 Maths Chapter 7 Congruence of Triangles
Triangles, as easy as they might look in structure and understanding, hold a lot of important properties. One such property of triangles is congruency which is discussed in the NCERT Solutions for Class 7 maths chapter 7 Congruence of Triangles. If any two objects are said to be congruent, that simply means that they are exact copies of one another. Even two line segments can be congruent if they possess the same length. This concept holds true for angles too. And similarly, it can be extended to even triangles. There are certain theorems that need to be considered while proving any two triangles as congruent. These are logically proved and explained in the NCERT solutions Class 7 maths chapter 7.
After going through the major concepts of congruence drafted in the chapter, the students will recognize the importance of superposition which is a handy way for determining whether any given two plane figures are congruent. After studying the congruency criteria for line segments, angles, and triangles, students can try applying this concept to other plane figures too. The Class 7 maths NCERT solutions chapter 7 Congruence of Triangle can be found in the link below and also find some of these in the exercises given below.

Topics Covered: The Class 7 maths NCERT solutions chapter 7 covers the congruence concept with the help of practical examples and activities starting from the basics of lines, angles, to triangles congruence. The SSS, SAS, ASA congruence theorems which form the base for proving triangles congruent, are discussed in detail, including the RHS congruence of right-angles too.
Total Questions: Class 7 maths chapter 7 Congruence of Triangles chapter 7 makes sure to cover all the congruence concepts in 14 questions, 12 of which are very simple, and include a few fill-in-the-blank questions also, the remaining two require the students to draw figures and solve the asked things henceforth.
List of Formulas in NCERT Solutions Class 7 Maths Chapter 7
The NCERT solutions Class 7 maths chapter 7 lays emphasis on the congruence theorems as mentioned above for proving the triangles as congruent. They are the SSS, SAS, ASA congruence theorems. Also, this has been explained for right-angled triangles as well. These important theorems covered in NCERT Solutions for Class 7 maths chapter 7 can be summarized as :
- Congruence Criterion: Two triangles are congruent if they tend to follow the hypothesis of the side-side-side(SSS), side-angle-side(SAS), angle-side-angle(ASA) theorem. SSS is stating that if the three sides of one triangle are equal to the three sides of the other, the two triangles are congruent. Similar postulates hold true for SAS and ASA as well.
- Right Angled Triangle Congruence: If the hypotenuse and a leg of one of the right-angled triangles are equal to the hypotenuse and the corresponding leg of the other triangle under a particular correspondence, then they are congruent.
