What polygons are regular?
What polygons are regular?
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star.
What polygon is not regular?
A polygon that does not have all sides equal and all angles equal. (A polygon is “regular” only when all angles are equal and all sides are equal, otherwise it is irregular.)
What is always true about a polygon that is regular?
A polygon is regular when all angles are equal and all sides are equal (otherwise it is “irregular”).
What must a regular polygon have?
To be a regular polygon, the flat, closed, straight-sided shape must also have another property. Every interior and exterior angle in the regular polygon is equal to every other interior and exterior angle, and every side is equal in length to every other side. A regular polygon has: Congruent (equal-length) sides.
What is a six sided polygon?
