How many degrees does a parallelogram have

WebWhen we have 3 consecutive vertices of a polygon \(A\), \(B\), and \(C\) so that the triangle \(ABC\) lies entirely inside the polygon, we call \(B\) an ear of the polygon. How many ears does a parallelogram have? Draw a quadrilateral that has fewer ears than a parallelogram. In 1975, Gary Meisters proved that every polygon has at least 2 ears. • Opposite sides of a parallelogram are parallel (by definition) and so will never intersect. • The area of a parallelogram is twice the area of a triangle created by one of its diagonals. • The area of a parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides.
