Objective:I know how to calculate the interior and exterior angles of polygons. The formula to find the sum of theinterior anglesof any polygon is sum of angles = (n- 2)180° , wherenis the number of sides of the polygon. The sum ofexterior anglesof any polygon is 360º. Read the...
The Exterior Angles of a Polygon add up to 360°In other words the exterior angles add up to one full revolution.Press Play button to see.(Exercise: try this with a square, then with some interesting polygon you invent yourself.)Note: This rule only works for simple polygons....
Now, remember this new rule above only applies to regular polygons. So, the only type of triangle we could be talking about is an equilateral one like the one pictured below. You might already know that the sum of the interior angles of a triangle measures 180∘180∘ and that in ...
