Answer 1

Pythagoras theorem states that in a right triangle(∆ABC). (angle ABC=90°) the square of the hypotenuse(AC) is equal to the sum of the square of the other two sides(AB &BC).

Converse of Pythagoras theorem states that if the square of the longest side (AC) is equal to the sum of the square of the other two sides (AB & BC) of a triangle(∆ABC), then it is a right triangle(THEN ANGLE ABC=90°).
