What is the smallest side?
A parallelogram with congruent diagonals.
What is a rectangle?
A regular polygon with each angle measuring 120 degrees.
What is a hexagon?
Lines that intersect to form a right angle.
What are perpendicular lines?

The sum of the exterior angles of any polygon.
What is 360 degrees?
