NCERT Solutions for Class 10th Maths Chapter 6 Triangles Exercise 6.1 Question 1

1. Fill in the blanks using the correct word given in brackets :

(i) 01:36 All circles are . (congruent, similar)

(ii) 02:15 All squares are . (similar, congruent)

(iii) 03:20 All triangles are similar. (isosceles, equilateral)

(iv) 04:00 Two polygons of the same number of sides are similar, if (a) their corresponding

angles are and (b) their corresponding sides are .(equal,

proportional)

All circles are similar because if we consider two circles with different radii, let it be r1 and r2. In this figure, r1 is not equal to r2. That means size of two circles is different. Two figures are said to be similar if their shape is similar. All circles are always similar.

All the squares are also similar.
