CONVERSE OF PYTHAGORAS THEOREM: In a triangle if square of one side is equal to the sum of the squares of the other two sides then the angle opposite to first side is a right angle. SOLUTION: Given : PQ = 24cm ,QR = 26cm, ? PAR = 90°, PA = 6cm and AR = 8cm. In ? PAR,, In the given figure, the triangle APR is right angled at ? A. Therefore , by pythagorean theorem : PR 2 = AP 2 + AR 2 ? PR 2 = 6 2 + 8 2 = 100 = 10 2 ? PR = 10 cm . Now , in triangle PQR PR = 10 cm , PQ = 24 cm , QR = 26 cm .
