Nov 06, 2007 · He is speaking of the exterior angles of a poloygon, not the interior of a triangle. Yes, the exterior of any said polygon will add up to 360 degrees. Even though dufis above some how thought you were lost, it's obvious that it's he that's lost, even though he's right about the sum of the angles of a triangle equaling 180degrees.

Nov 08, 2020 · Understand what makes a polygon "regular". A regular polygon is one where all of the sides and all of the angles are the same length. Perhaps the easiest regular polygons to identify are the equilateral triangle (with three sides of the same length and internal angles of 60 degrees each) and the square (with four sides of the same length and internal angles of 90 degrees each).

Polygons can be regular or irregular. Regular polygons have all sides of equal length and all angles of equal size. Irregular polygons have sides of unequal length and angles of unequal size. Sometimes we can think irregular shapes are not ‘proper’ as they look different to the more common ones.

A regular polygon is a polygon that is both equiangular and equilateral. All sides are equal length placed around a common center so that all angles between sides are also equal. When the number of sides, n, is equal to 3 it is an equilateral triangle and when n = 4 is is a square .
