yes the radius of a regular polygon is always greater than the apothem
Chat with our AI personalities
A Square is a polygon that is always regular.
An apothem is the red segment in the diagram (Figure1). B is the center point of the hexagon, and the blue line are radii of the polygon. An apothem is always from the center of the polygon, to the outside, and it is always perpandicular to the side it is touching. You find the area of any polygonwith this equation: (.5) n a s In the formula, n= number of sides, a= the length of the apothem, and s= the length of any given side.

No, a scalene triangle, for example, is a convex poygon but it is not regular.
Hint: in a regular polygon interior plus exterior = 180o, always.
A quadrilateral, a parallelogram, a rhombus, a rectangle, a regular polygon.
