1.	POR is an isosceles right triangle right angled at R. P,rovethatExercise 12 (E)The lengths of three sides of a triangle are givelow. Find which can form a right triangle.(a)2.5 cm, 6.5 cm, 6 cm(b) 11 cm, 60 cm, 61 cme) 2 cm, 2 cm, 5 cm
Answer» (6)(6)+(2.5)(2.5) = 36 + 6.25 = 42.25 = (6.5)(6.5) so yes it is right angled triangle (11)(11) + (60)(60) = 121 + 3600 = 3721 = (61)(61) so yes it is right angled triangle (2)(2) + (2)(2) = 4 + 4 = 8 which is not equal to 5*5 = 25 so it is not right angled triangle.
