Answer:
Each leg must be greater than 7.
Explanation:
In a triangle, the sum of the two sides must be greater than the third side.
If a, b and c are sides of the triangle, the following conditions must be satisfied.
i) a + b > c
ii) b + c > a
iii) c + a > b
It must be true for all the triangles.
We are given an isosceles triangle, in the isosceles triangle, two sides must be equal.
We are given the base as 14 units.
So, the sum of the lengths of the other two sides must be greater than 14.
Therefore, each leg must be greater than 7.
