Geometry Chapter 14

Regular polygons are Convex, equilateral, equiangular
Every regular polygons is cyclic
The perimeter of a regular polygon depends on two things: The radius, the number of sides
perimeter of a regular polygon 2nrsin(180/n)
Area of a triangle= 1/2(rsqrt3/2)(r/2)
Area of a regular polygon nr^2sin(180/n)cos(180/n)
Circumference of a circle= 2rπ
Circumference of a circle also=
Area of a circle= πr^2
A sector is bounded by two radii and an arc
Area of a sector= x/360πr^2
Arc length= x/360(2)πr
