Step-by-step explanation:
How Far Apart are the Dots?
Q. Guess the distance between any two dots. How many centimeters is it? Now measure it with the help of a scale. Did you guess right?
Ans. The guessed distances between any two dots are:
Between dots
A and B = 3 cm,A and C = 4 cm,A and D = 4.5 cm
A and E = 4 cm,A and F = 4.5 cm,A and G = 6 cm
A and H = 5 cm,B and C = 6 cm,B and D = 5 cm
B and E = 5 cm,B and F = 8 cm,B and G = 3 cm
Band H = 7 cm,C and D = 8 cm,C and E = 5 cm
C and F = 3 cm,C and G = 8 cm,C and H = 5.5 cm
D and E = 7 cm,D and F = 9 cm,D and G = 4cm
D and H = 9 cm,E and F = 5 cm,E and G = 5 cm
E and H = 3 cm,F and G = 9 cm,F and H = 3.5 cm
G and H = 7 cm,
On actual measurement, we find the distances between the do’s as under :
Between dots
A and B = 3 cm,A and C = 3 cm,A and D = 4.4 cm
A and E = 3.5 cm,A and F = 4.6 cm,A and G = 6.3 cm
A and H = 6 cm,B and C = 5.8 cm,B and D = 4.8 cm
B and E = 5 cm,B and F = 7.2 cm,B and G = 3.2 cm
B and H = 7 cm,C and D = 6.8 cm,C and E = 5.2 cm
C and F = 2.5 cm,C and G = 7.7 cm,C and H = 5 cm
D and E = 6.8 cm,D and F = 8.5 cm,D and G = 4.2 cm
D and H = 8.8 cm,E and F = 4.8 cm,E and G = 4.5 cm
E and H = 2.6 cm,F and G = 8.5 cm,F and H = 3.5 cm
G and H = 7.2 cm,
We see that the guesses are almost right.
