In the given figure,3 squares are fitted together. Some lines are drawn. What is the value of $\alpha +\beta +\gamma$?
I just can derive alpha as 45 degree as it is an angle formed by diagonal of square. How to find the other two?
I have seen similar questions that were solved using trigonometry. I just want the process how to solve it by using only elementary geometry.
Also I saw another problem that answered its complements but I can't understand it
