A concave polygon is always an irregular polygon. The following are a few examples. A regular polygon is always convex. When the two lines are parallel, any pair of Consecutive Interior Angles add to … 8. So . The difference between any two consecutive interior angles of a polygon is 5°. One way to get the recurrence formula is observing that if ϕ is the angle between two consecutive vertices of a regular polygon inscribed in the circle of radius one, then half of a side is equal to sin (ϕ / 2) Thus, if we denote by ln the length of one side of the regular n-sided polygon, we obtain the formula Consecutive angles of a parallelogram Two interior angles of a parallelogram are called the consecutive angles if some side of the parallelogram is the common side of these two angles. View solution. Convex Polygon A polygon whose interior angles are all less than 180 degrees. Consecutive angles in Geometry are tha angles at each end of one side. The sum of interior angles is $$(6 - 2) \times 180 = 720^\circ$$.. One interior angle is $$720 \div 6 = 120^\circ$$.. You can name a polygon by the number of its sides. So we can say that in a plane, a closed figure with many angles is called a polygon. sides. If the smallest angle is 120 , find the number of the sides of the polygon. 14. Dividing a polygon with n sides into (n − 2) triangles shows that the sum of the measures of the interior angles of a polygon is a multiple of 180°. space. a polygon is a dead parrot! Definitions .
