They are plane figures
They are closed
They are bounded by 3 or more straight sides
They have the same number of sides as vertices
Their exterior angles add to 360 degrees
Their interior angles add to (n-2)*180 degrees, where n is the number of sides
irregular polygons don;t have equal angles
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.
Polygons that fit together with no gaps or overlaps are said to tessellate with each other.
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.
That they all have the same shape and sometimes size
irregular polygons don;t have equal angles
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
Their sides are proportional and their interior angles are the same
