So i,must prove that it should be 60 degree, basically in an equilateral triangle all sides are equal so take any triangle and measure them and conclude yourself elwhich is the longest side and add other two sides and they will more than the longest side, hence your statemment is applicable only for equilateral triangle.

Ashok Meena Arunnachalam 6 years, 2 months ago

Your answer was nice karya agrawal but thinking practically i can say that when you draw a right angle to join the ends yoy need to draw a line and after measuring the line hypotenus is longer abd it is a line joining a perpendicular point

Kavya Agrawal 6 years, 2 months ago

Let other two angles be x and y. Now, 90 + x + y = 180 x + y = 90 Therefore, 90>x 90>y Therefore, Side opposite to the largest angle (90) is the longest that is the hypotenuse.

Excellent kavya but exterior angle is equal to sun of two opposite interior angles so x=a+b,so a+b,40+55=95,sox=95

Kavya Agrawal 6 years, 2 months ago

A + B + C = 180 40 + 55 + C = 180 95 + C = 180 C = 180 - 95 = 85 Exterior angle of C = X = 180- C X = 180 - 85 X = 95
