can you please send to me a formalize proof for the assertion that, the sum of angles in a square is three hundred and sixty degrees. i will be grateful to hear from you
I suppose the easiest proof is by using definitions definition:
A square is defined as a particular kind of rectangle.
A rectangle is defined as a closed planar quadrilateral where
opposite sides have the same length and each of the four interior
angles is 90 degrees.
Therefore the sum of the interior angles of a square is 90 + 90 +
90 + 90 = 360.
