NCERT Class 9 Maths Chapter 5 Introduction to Euclid's Geometry Solutions
NCERT Class 9 Maths Chapter 5 Introduction to Euclid's Geometry Solutions Exercise 5.1 Q.1. Which of the following statements are true and which are false? Give reasons for your answers. (i) Only one line can pass through a single point. Ans: False, from one point an infinite number of lines can pass. (ii) There are an infinite number of lines which pass through two distinct points. Ans: False, as from two distinct points only one line can pass through them. (iii) A terminated line can be produced indefinitely on both sides. Ans: True, as you can see in the figure. (iv) If two circles are equal then their radii are equal. Ans: True, if two circles are equal then their centre and circumference will coincide. Therefore, radii will be equal. (v) In fig. 5.21, If AB = PQ and PQ =XY then AB = XY. Ans: True. As AB = PQ and PQ = XY Therefore, comparing figures of (a) and (b) we get AB = XY. Q.2. Give definition for each of the following terms. Are there other terms that need to be define...
