www.math.tamu.eduThe central angles of a regular polygon are congruent. The apothems of a regular polygon are contained in the perpendicular bisectors of each side. Each apothem of a regular polygon bisects the central angle whose rays intersect the polygon at the vertices of the side to which the apothem is drawn.

ncert.nic.inA polygon is said to be regular if all its sides are of equal length and all its angles are of equal measure. Thus, an equilateral triangle is a regular polygon of three sides. Can you name the regular polygon of four sides? An equilateral triangle is regular because each of its sides has same length and each of its angles measures 60° (Fig 14.2).

www.exploratorium.educircle by using the Pythagorean Theorem to find the areas of two regular polygons: the polygon inscribed within the circle and the polygon within which the circle was circumscribed. Since the actual area of the circle lies between the areas of the inscribed and circumscribed polygons, the areas of the polygons gave upper and lower bounds for
