    • Polygon Interior Angles Theorem is the sum of the interior angles of a polygon= (n-2)180
    • The formula for Regular Polygon Interior Angles is (n-2)180/n
    • Polygon Exterior Angles Theorem says the exterior angles of a polygon equal 360 degrees
    • The apothem is the distance from the center to the side of a polygon
    • The area of a Regular N-gon is A=aP/2
    • The area of an equilateral triangle is solved with A=(s²√3)/4
    • To find the measure of a central angle use 360/n
    • Euler's Theorem is F+V=E+2
    • A solid is a 3d shape and a polyhedron
    • A regular polyhedron has congruent faces, angles, and sides
    • A convex polyhedron has (any) two points on its surface that can be connected by an inside segment
    • A concave polyhedron has two points on its surface that when connected go outside the shape
    • Polyhedron can't have curved edges and must be bound by polygons
