State Pythagoras theorem and its converse.
Solution:
TO STATE: Pythagoras theorem and its converse.
PYTHAGORAS THEOREM: In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
hypotenuse $^{2}=$ perpendicular $^{2}+$ base $^{2}$
CONVERSE OF PYTHAGORAS THEOREM: In a triangle, if the square of one side is equal to the sum of the square of the other two sides then the angle opposite to the greatest side is a right angle.
