Pythagoras Theorem

          

Pythagoras Theorem:In any right angled triangle, the square made on the longest side (Hypotenuse) is equal to the sum of the squares made on the remaining two sides (Perpendicular and Base).

Mathematically:                                           

1) h² = p² + b²
 

Similarly:

2) p² = h² - b²

3) b² = h² - p²

Trigonometric Ratios

Today we are going to discuss trigonometric ratios. As we all know that a right-angled triangle has 3 sides and three angles. Using those 3 sides we can obtain six ratios. Which are called trigonometric ratios.
