No, because we can double the length of the sides of the 345 triangle and still have a rightangled triangle its sides will be 6810 and we can check that 10 2 = 6 2 8 2 Continuing this process by tripling 345 and quadrupling and so on we (ii) 3 cm, 8 cm, 6 cm Given sides 3 cm , 8 cm , 6 cm Using Pythagoras theorem , (Hypotenuse)2 = (Height )2 (Base)2 Here , Hypotenuse Is largest side that is 8 cm Since LHS ≠ RHS , Pythagoras theorem is not satisfied Hence the given triangle is not a right angled triangle Ex 65,1 Sides of triangles are given belowWhich pair of angles are congruent?
