What is known as pythagoras theorem?

Yes you heard it right Pythagoras just came up with the concept in terms of mathematics but it was a original idea used by the Egyptians 2500 years ago to build their pyramids and the same concept was used to build some of the masterpiece temples of south India. The concept is simple, for a triangle with one angle equal to 90° if you add square of smallest side to square of medium side you will get square of longest side i.e. base^{2} + perpendicular^{2} = hypotenuse^{2} And it's not only a maths formulae to just mug up it's the most practically applicable formulae eg: 1. In advertisements the the size of tv shown is actually the length of diagonal of its screen and to check it's real size as per your tv cabinet at home just apply Pythagorean principle to your tv cabinet and calculate it's diagonal size and voila you will know if your tv is going to fit in that cabinet or not. 2. Painters use the same concept to place their ladder at safe position while painting a wall. 3. The suspension bridges (eg. The ones you see with wires support) use this concept. There are a thousand examples where Pythagorean principle is used all you need is a practical mathematical sense. Take care and keep learning. read less

Phythagoras theorem states that in a right angled triangle ( one of the angles is 90* ) the sum of sqaures of the perpendicular side and the base of the triangle is equal to the square of the hypotenuse i.e (P)2 + (B)2 = (H)2 This theorem is most likely to be asked in exams and is generally asked to state and prove the theorem. Also the theorem has many applicability scenarios and is exam question paper is incomplete with out it. * the important thing while solving questions is to make sure that you observe the Base, perpendicular and hypotenuse carefully. read less
