More about this book
Most students read the textbook once and run out of time for a second revision. This formula sheet book is made for that gap: it keeps only what the exam asks, in the same order as the NCERT chapters, so you can revise the full syllabus three or four times before the exam.

2.3 BAUDHAYANA'S THEOREM ON RIGHT TRIANGLES
We have seen that the square of a number can be represented as the area of a square whose side is that number. Let us now consider a right-angled triangle and draw squares on each of its three sides. If the two shorter sides of the triangle are 3 units and 4 units long, the areas of the squares drawn on them are 9 square units and 16 square units. The square drawn on the longest side, the hypotenuse, turns out to have an area of 25 square units, which is exactly the sum of the other two.
This relation was stated in the Baudhayana Sulba-Sutra, composed in India many centuries ago, in the following words: the areas produced separately by the length and the breadth of a rectangle together equal the area produced by the diagonal. The same result is widely known today as the Pythagoras theorem. If a and b are the lengths of the two legs and c the length of the hypotenuse, then
The theorem allows us to find the length of any one side of a right triangle when the other two are known. For example, if the legs are 5 cm and 12 cm, then c² = 25 + 144 = 169, so c = 13 cm.
