Four points are placed on a circle. How many segments will it take to connect each point to every other point?
alexandr1967 [171]

Answer:

6 segments are required to connect each point to every other point.

Step-by-step explanation:

If four points are placed on a circle.Then as we know the segment is a line that join two points.

Now as we are given four points on the circle.

  • so we will firstly start with the first point; the first point requires 3 segments to connect to the remaining three points.
  • Next second point will just require 2 segments to connect to the two points as it is already connected to the first point.
  • similarly third point requires just one segment to connect to the last point as it is already connected to first and second point as done above.
  • and hence by the above three steps the fourth point is connected to all the points.

Hence, 6 segments are required to connect each point to every other point.
