How many number of sides does a polygon have? – Quick-Advices
WebIts accepted mathematical definition is any figure that has more than two sides and which forms a closed figure is called polygon. Hence, polygon can have three and many more but finite sides. A three-sided polygon is called a triangle. The four-sided quadrilateral is a polygon. The figures are named by attaching a numerical prefix to the polygon. WebAnswer (1 of 3): sum of exterior angles = 360 Sum of interior angles = (n - 2)180, where n = the number of sides. So, we have this equation: 360 = [(n - 2)180] - 180 Solving for n: 360 = 180n - 360 - 180 360 = 180n - 540 180n = 900 n = 900/180 = 5 Conclusion: The convex polygon has 5 sid... how many more days till march 1
