    the answer is

    I say 60 degrees!

    Explanation -

    1. The two diagonals will form two sides of the triangle.
    2. Third side will be the line joining two ends of these diagonals. So it will be the third diagonal.
    3. Triangle thus formed, will be an equilateral triangle.
    4. Therefore the angle included will be 60 degrees ! 😀
    It was easy. We can have a thread similar to Neha's games on vocab. A quantitative discussion thread. 😉
