Triangle Formation using the Points of a Square
To solve this problem, let's consider the given points: the four vertices of a square (A, B, C, and D) and the intersection point of its diagonals (O). We need to determine the number of triangles that can be formed using these points.
Identification of Triangles
To find the number of triangles, we need to identify all the possible combinations of three points among the given points. Since a triangle is formed by connecting three non-collinear points, we can select any three points from the given five points to form a triangle.
Forming Triangles
Let's consider all the possible combinations of three points from the given five points:
1. Triangle formed with A, B, and C.
2. Triangle formed with A, B, and D.
3. Triangle formed with A, B, and O.
4. Triangle formed with A, C, and D.
5. Triangle formed with A, C, and O.
6. Triangle formed with A, D, and O.
7. Triangle formed with B, C, and D.
8. Triangle formed with B, C, and O.
9. Triangle formed with B, D, and O.
10. Triangle formed with C, D, and O.
Counting the Triangles
From the above combinations, we can see that a total of 10 triangles can be formed using the given points. Therefore, the correct answer is option 'C' - 8.
Conclusion
In this problem, we considered the vertices of a square and the intersection point of its diagonals. By identifying all the possible combinations of three points, we determined that a total of 10 triangles can be formed using these points.

We can form a triangle by choosing 3 points out of 5
Total triangles = 5C3 = 10
But in this, 3 points are collinear in the cases of the 2 diagonals and must be excluded.
So, total triangles = 10 -2 = 8.
