A regular polygon is a
polygon where all sides and
A polygon is a shape with 3
angles are equal
Ex. Square and Equilateral
Triangles
A quadrilateral is a 4
sided polygon with 4
angles that always add
up to 360
or more straights sides that
is closed. NO curves.
A triangle is a 3 sided
polygon with 3 angles that
always add up to 180
What does it mean if
