Dear All Believe it or not, three legged stool is more stable than any other stool. The principle underlying is this fact is we can draw only one cirlcle through three given points which are not collinear. That is why old people walk with the assistance of a stick (third leg) , or even think of tripod.

Dear All What is the largest number of circles that can touch another circle of equal size? The answer is 6. In case of spheres this number is 12 (total 13). Newton discovered this property in 1694. Believe it or not this property was proved by R. Hoppe only in 1874 after 180 years of its discovery.

Dear All There are only five Heronian triangles (triangles having integer sides) such that the perimeter is equal to the area. They are : (5, 12, 13) , (6, 8, 10) , (6, 25, 29) , (7, 15, 20) and (9, 10, 17). The first two triangles are right triangles also.

Dear All Do you think that anything and everything in Mathematics has been discovered till date, or is there a scope for NEWER Maths? Read below and then think again!!! The number of periodicals that publish mathematical research papers and articles are given below: Prior to 1700 AD 17 periodicals 18th Century 210 periodicals 19th Century 950 periodicals 20th Century 2000 periodicals According to one estimate every year nearly 2,00,000 (two lakhs, no typing mistake) new theorems and methods appear in the journals and the books. So... What are you thinking? To derive a new maths formula or result! Good luck!

Dear All Most of us know that the sum of two sides of any triangle is greater than the third side. But very few of us know that the sum of three sides of a triangle is greater than the sum of the bisectors of the angles of the triangle . Well... whats about the relationship between four sides of any quadrilateral? any guess.... yes, you are right.... The sum of any three sides of a quadrilateral is always greater than the fourth side.

Dear All Believe it or not there is no equilateral triangle , the coordinates of whose vertices are all integers. Well... it can be proved very easily. Try it!
