Basic Concepts Number of Sections
When drawing a line from one point to another in a circle, intersecting points
and sections are formed.
Intersecting Points: 4 Intersecting Points: 3 Intersecting Points: 5
Sections: 3 Sections: 3 Sections: 4
Example In the box below, 2 and 3 sections are formed by two squares of
equal size. Find all possible numbers of sections that can be
formed by these two squares of equal size.
2 sections 3 sections
Class Notes
Two squares of equal size can form the sections as shown below.
sections 5 sections sections
sections sections 9 sections
