Access Answers to NCERT Class 7 Maths Chapter 7 – Congruence of Triangles Exercise 7.1

1. Complete the following statements:

(a) Two line segments are congruent if ___________.

Solution:-

Two line segments are congruent if they have the same length.

(b) Among two congruent angles, one has a measure of 70o; the measure of the other angle is ___________.

Solution:-

Among two congruent angles, one has a measure of 70o; the measure of the other angle is 70o.

Because, if two angles have the same measure, they are congruent. Also, if two angles are congruent, their measure is the same.

(c) When we write ∠A = ∠B, we actually mean.

Solution:-

When we write ∠A = ∠B, we actually mean m ∠A = m ∠B.

2. Give any two real-life examples for congruent shapes.

Solution:-

Two real-life examples for congruent shapes are

(i) Fan feathers of the same brand.

(ii) Size of chocolate in the same brand.

(iii) Size of pens in the same brand

3. If ΔABC ≅ ΔFED under the correspondence ABC ↔ FED, write all the corresponding congruent parts of the triangles.

Solution:-

Two triangles are congruent if pairs of corresponding sides and corresponding angles are equal.

All the corresponding congruent parts of the triangles are,

∠A ↔ ∠F, ∠B ↔ ∠E, ∠C ↔ ∠D

Correspondence between sides:
