Why we cannot construct a triangle with sides 5 cm, 5 cm and 10 cm?

Because sum of two sides of triangle should be more than the third side ...but in this case 10 = 5+5
Thus, we cannot construct a ∆ having its sides 10cm , 5cm and 5cm

Because It doesn't follow the triangles property which states that, the sum of two sides of triangle is greater than the third side and the difference of the two side is smaller than the third side.
