A polygon is a closed plane figure that is bounded by straight sides. There may be three or more sides - up to any number. The sides can be the same size or different. It must have the same number of sides as vertices. The angles may be the same or different. The sum of the exterior angles is 2*pi radians. The sum of the interior angles of a polygon with n sides is (n-2)*pi radians.
1 radian = 180 degrees.
square triangle and etc
he made the properties of the polygons.
a polyhedron is any 3d figure with all flat polygons for sides(polygons have straight sides)
They are all polygons having their own particular properties
That they all have the same shape and sometimes size
The properties of polygons predate you - or any other person. You cannot prepare them, they exist as they are with or without you.
irregular polygons don;t have equal angles
That they all have the same shape and sometimes size
That they all have the same shape and sometimes size
It's quite acceptable to call them 20-29agons but what's more important is knowing how to work out their properties
Basically it is working out the properties of triangles and angles of various polygons.
Their sides are proportional and their interior angles are the same
