Pythagoras Theorem ICSE Class-9th RS Aggarwal Mathematics Solutions Goyal Brothers Prakashan Chapter-10


 Statement of Pythagoras Theorem

Pythagoras theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangles have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°

Applications of Pythagoras Theorem

 

  • To know if the triangle is a right-angled triangle or not.
  • In a right-angled triangle, we can calculate the length of any side if the other two sides are given.
  • To find the diagonal of a square.
