The Triangle Problem
Given above is an equilateral triangle of side 6 units.5 parallel lines are drawn to each side of the triangle at a distance of 1 cm to form a grid like above. Find the number of parallelograms formed in the triangle. Given that only squares,rectangles etc. are not parallelograms Note-This is a combinatorial question.....don't waste your time counting all the parallelograms P.S.-The figure is just to give a hint of what the situation will actually look like....
The answer is 210.
