NCERT Solutions for Class 7 Maths Chapter 7: Congruence of Triangles

Get

When two line segments have equal length, they are called congruent. When the measure of two angles is equal, then the angles are called congruent. The relation between two objects being congruent is known as congruence. The first Exercise, 7.1, contains topics related to plane figures, congruence among line segments, and triangles' congruence. The shortest distance between two lines is called the line segment. Two rays having the same vertex form an angle. When a plain figure covers the other exactly, they are of the same shape and size. Such an object is known as congruent.

In Ex 7.2, two covered topics are criteria for congruence of triangle and congruence among right-angled triangles. A triangle can be considered congruent when both the angles are identical or equal in all aspects. You will study about the 4 rule of congruence that is Side-side-side [SSS criterion], Side-angle-side [SAS criterion], Angle-side-angle [ASA criterion], right angle-hypotenuse-side [RHS criterion]. The main topic in this chapter are:

  • Congruence of plane figures
  • Congruence among line segments
  • Congruence of angles
  • Congruence of triangles
  • Criteria for congruence of triangle
  • Congruence among right-angled triangles.
