Andy took three sticks of 3m, 4m and 5m. He was sure that he will be able to make a triangle and he could make the triangle.
True
To construct a triangle, sum of the length of two sides should be greater than the third side.
So, the sum of the length of two sticks is greater than the third side.
4 m + 3m ˃ 5 m
3m + 5m > 4m
5m + 4m > 3m
So, this time, Andy will be able to construct a triangle.
