**the answer is**

I say 60 degrees!

Explanation -

- The two diagonals will form two sides of the triangle.
- Third side will be the line joining two ends of these diagonals. So it will be the third diagonal.
- Triangle thus formed, will be an equilateral triangle.
- Therefore the angle included will be 60 degrees ! 馃榾
