NCERT Class 6 Mathematics Fifth Chapter Understanding Elementary Shapes Exercise 5.1 Solutions

EXERCISE 5.1

(1) What is the disadvantage in comparing line segments by mere observation?

 (2) Why is it better to use a divider than a ruler, while measuring the length of a line segment?

(4) If A,B,C are three points on a line such that AB = 5 cm, BC = 3 cm and AC = 8 cm, which one of them lies between the other two?

Ans: Point B lies between the A and C.

(6) If B is the mid point of AC and C is the mid point of BD, where A,B,C,D lie on a straight line, say why AB = CD?

Ans: AB = BC and BC = CD; therefore AB = CD

(7) Draw five triangles and measure their sides. Check in each case, if the sum of the lengths of any two sides is always less than the third side.
