Being a square having 4 equal sides and 4 equal angles. It follows that the diagonal formed a angle =

To prove this using Trigo functions, and based on a 12 inch square tile:

Solving for Diagonal: (Pyth Theorem)

By Trigo function, (Sine-Cosine-Tangent)

, correct (angle formed by the diagonal and the side)

, correct

, correct
