If I have a square and I draw two lines across the middle that interestect what would be the interior angles of that intersection. I know the square itself is 360 degrees and the inner corners are all 45 degrees. I am not sure how to calculate the interior ones.
ex Suppose polygon wxyz is any square with diagonals wy and xz intersecting at point G.
What is the measure of angle xGz?

The two diagonals cross in the middle of the square. All the angles at the intersection are the same. The four of them add up to 360 degrees. 360/4
