1. How Far apart are the Dots?
• Guess the distance between any two dots.
How many centimetres is it? Now measure it with the help of a scale. Did you guess right?
Ans. The guess distance between any two dots are:
A to B = 3 cm B to C = 5 cm C to D = 7cm
A to C = 3 cm B to D = 2 cm C to E = 5.5cm
A to D = 4.5cm B to E = 5 cm C to F = 2.5cm
A to E = 3.5cm B to F = 7.5cm C to G = 8cm
A to F = 4.5cm B to G = 3 cm C to H = 5cm
A to G = 5 cm B to H = 7 cm C to I = 4.5cm
A to H = 5 cm B to I = 2 cm C to J = 4cm
A to I = 2 cm B to J = 4.5cm C to K = 3cm
A to J = 1.5cm B to K = 6.5cm C to L = 6.5cm
A to K = 4 cm B to L = 2 cm C to M = 2.5cm
A to L = 3.5cm B to M =J5 cm C to N = 3cm
A to M = 5 cm B to N = 6cm C to 0 = 8cm
A to N = 3 cm B to 0=2.5cm
A to 0 = 5 cm
• Similarly guess the distances between other dots and make the The actual distances between any two dots are:
A to B = 3 cm B to C = 5.8cm C to D = 6.8cm
D to K = 7.5cm H to O = 9.5cm D to H = 9cm
G to K = 9 cm G to M = 9.6cm O to M = 10cm
O to H = 9.5cm K to H = 6cm M to H = 4.7cm
O to D = 1 cm
2. Measure the distance similarly between other dots and write them in the table.
Ans. Attempt yourself.
• Which two dots do you think are farthest from each other ? Check your answer.
Ans. Dots M and O are farthest from each other. The distance between M and O is 10
• Which two dots are nearest to each other? Check your answer.
