Step-by-step explanation:
The sum of the measures of the angles of a convex quadrilateral is 360 as a convex quadrilateral is made of two triangles.
If ABCD is a convex quadrilateral, made of two triangles ABD and BCD. Therefore, the sum of all the interior angles of this quadrilateral will be same as the sum of all the interior angles of these two triangles i.e., 180+180=360
Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.
