Alternate interior angles are congruent. So, angle 3 = angle 7.
We see that vertical angles are congruent. So, angle 3 also = angle 5.
Alternate exterior angles are congruent.
So, angle 3 also = angle 1.
Diagonals = n(n-3)/n where n is the number of sides
if a polygon have 10 sides
= 10(10-3)/10
= 7
thus, the polygon have 7 diagonals.
