WebIn a convex quadrilateral all interior angles are less than 180°, and the two diagonals both lie inside the quadrilateral. Irregular quadrilateral ( British English) or trapezium ( North American English ): no sides are parallel. (In British English, this was once called a trapezoid. For more, see Trapezoid § Trapezium vs Trapezoid) WebTo find the measure of angle DAC, we must know that the interior angles of all triangles sum up to 180 degrees. Also, as this is an isosceles trapezoid, and are equal to each other. The two diagonals within the trapezoid bisect angles and at the same angle. Thus, must also be equal to 50 degrees. Thus, .
