Consider a rectangle ABCD having 5, 7, 6, 9 points in the interior of ...
Us assume that the points inside the line segment AB divide it into 6 smaller line segments, and similarly for the other line segments.
Let's consider the line segment AB. It is divided into 6 smaller line segments by the 5 points in its interior. This means that there are 6 + 1 = 7 line segments in total. Similarly, there are 8 line segments in the line segment CD, 7 line segments in BC, and 10 line segments in DA.
Now, let's consider the interior of the rectangle ABCD. It is divided into two parts - the interior of the line segment AB and the interior of the line segment CD. The interior of the line segment AB has 5 points and 7 smaller line segments, while the interior of the line segment CD has 6 points and 8 smaller line segments.
Therefore, the total number of points in the interior of the rectangle ABCD is 5 + 6 = 11, and the total number of smaller line segments is 7 + 8 = 15.
Hence, the total number of points and smaller line segments in the interior of the rectangle ABCD is 11 + 15 = 26.

Consider a rectangle ABCD having 5, 7, 6, 9 points in the interior of ...
α = Number of triangles
α = 6C1 7C1 9C1 + 5C1 7C1 9C1 + 5C1 6C1 9C1 + 5C1 6C1 7C1
= 6.7.9 + 5.7.9 + 5.6.9 + 5.6.7
= 378 + 315 + 270 + 210
= 1173
β = Number of quadrilaterals
β = 5.6.7.9 = 1890
β - α = 1890 - 1173 = 717
