+Polygon
A polygon is regular when all angles are equal and all sides are equal
Example: square, equilateral triangle, pentagon, hexagon, heptagon, octagon

+Quadrilateral
A flat shape with four straight sides
Examples: Squares, Rectangles, Rhombus, Trapezoid, Parallelogram

+Square A 4-sided flat shape with straight sides where:
• all sides have equal length, and• every interior angle is a right angle (90°)
It is a Quadrilateral and a Regular Polygon

+Perimeter
The distance around a two-dimensional shape.
Perimeter
Example: the perimeter of this rectangle is 3+7+3+7 = 20

+Perimeter of a Square
P=S+S+S+S or P=4s
Perimeter is measured in units

+Rectangle
A 4-sided flat shape with straight sides where all interior angles are right angles (90°).
Also opposite sides are parallel and of equal length.

+Perimeter of a Rectangle
P=S+S+S+S or P= 2(Length)+2(Width)
Perimeter is measured in units
