### interior and exterior angles of polygons

Sum of the exterior angles of a polygon (Hindi) Our mission is to provide a free, world-class education to anyone, anywhere. Questions: 1) As you increase the number of sides of the polygon, how does the sum of the interior angles change? The interior angle concept can be extended in a consistent way to crossed polygons such as star polygons by using the concept of directed angles. Students also learn the following formulas related to convex polygons. To show the exterior angles you have more choices, use the select control to choose the exterior angles clockwise or anticlockwise. Another example: When we add up the Interior Angle and Exterior Angle we get a straight line 180°. Sum of interior angles of a three sided polygon can be calculated using the formula as: Sum of interior angles = (p - 2) 180° 60° + 40° + (x + 83)° = (3 - 2) 180° 183° + x = 180° x = 180° - 183. x = -3. Q. Polygons are like the little houses of two-dimensional geometry world. Angles in Polygons Worksheets. Students use the properties of regular polygons to calculate interior and exterior angles. Regular Polygons. Finding the interior angles of a polygon. Remember, the sum of the exterior angles of ANY polygon is always 360 degrees. They are "Supplementary Angles". Click the checkboxes next to the drawing to make the interior or exterior angles visible. Here is a complete lesson on calculating the interior and exterior angles of a polygon. Various angle types can be displayed. WORKSHEET: Angles of Polygons - Review PERIOD: DATE: USING THE INTERIOR & EXTERIOR ANGLE SUM THEOREMS 1) The measure of one exterior angle of a regular polygon is given.
