Outer Angles of a Polygon
Learning Outcomes: Understanding about the concept of Outer Angles of Polygons Establishing the relationship between interior angles and exterior angles of Polygons Visualize the Outer Angle Sum of Polygons Applying the concept of outer angle sum in problem solving Class Notes Definition and meaning The Angles formed outside a Polygon by extending one side of the Polygon is called Outer Angles. Inner Angle + Outer Angle = 180° Sum of Outer Angles of a Polygon= Angle around a point =360° Video https://youtu.be/h_9vTeDLlqw?si=xaqPNFsvqMh8Ns8h Quick Check 1.What is the outer angle sum of the following Polygons? 2.If the one of the outer angle of a regular polygon is 30 °,then how many sides does it have? (a)12 (b) 24 (c) 10 (d) 30 3. What is the inner angle of a Polygon, whose outer angle is 60°?
