Justify Conclusions take a conjecture about the sum of th interior angles of a quadrilateral. Justify your reasoning.

A quadrilateral can be divided into two triangles but drawing one of its diagonals. Since the sum of the interior angles of a triangle is 180°, then we conjecture that the sum of the interior angles of a quadrilateral is $$\displaystyle{2}{\left({180}°\right)}={360}°.$$
