A quadrilateral can be divided with a diagonal into two triangles each with an interior angle sum of 180

Explanation: If you accept that the interior angles of a triangle add up to 180

Interior angles of △ABD=p+q+r=180

Interior angles of △DBC=u+s+t=180

Interior angles of □ABCD=p+q+r+u+s+t=180+180 =360
