There are 7 dots on a piece of paper. No 3 dots are in a straight line. How many line segments are needed to connect each dot to

AleksandrR [38]

21 line segments are needed to connect each dot to each other dot.

Since, there are 7 dots on a piece of paper such that no 3 dots are in a straight line.

We know that a line segment has two endpoints.

Number of line segments formed by <em>n</em> points = $\dfrac{n(n-1)}{2}$

So the required number of line segments are needed to connect given 7 dots (each dot to each other dot ) $=\dfrac{7(7-1)}{2}$

$=\dfrac{7\times6}{2}$

$=21$

Hence, 21 line segments are needed to connect each dot to each other dot.
