Question

# Consider the five points comprising of the vertices of a square and the intersection point of its diagonals. How many triangles can be formed using these points?

Solution

## To form a triangle, $$3$$ points out of $$5$$ can be chosen in $$^{5}C_{3} = 10$$ ways.But of these, the three points lying on the $$2$$ diagonals will be collinear.So $$10 - 2 = 8$$ triangles can be formed.Maths
