In broadest terms, what quadrilateral has 2 pairs of opposite sides that are congruent and 4 right angles?
Rectangles
True or False: If all sides of two parallelograms are congruent, then the parallelograms are congruent.
False
True or False: Knowing that a quadrilateral has bisecting diagonals is enough to know it's a parallelogram
True
True or false: Like a square, the diagonals of a rectangle are congruent
True
What is the term for any polygon that is both equiangular and equilateral?
Regular
This quadrilateral has 4 congruent sides, the opposite sides are parallel, and doesn't necessarily have right angles.
What is rhombus?
These quadrilaterals have exactly one pair of parallel sides.
What are trapezoids?
In broadest/most inclusive terms, these quadrilaterals' diagonals are angle bisectors.

Rectangles
What is the term for a polygon with no reflex angles?
Convex
True or False: Knowing that a quadrilateral has supplementary adjacent angles is enough to know it's a parallelogram
False
What is the sum of the exterior angles of a dodecagon?
360
These quadrilaterals have two pairs of adjacent sides that are congruent.
What are kites?
These quadrilaterals diagonals bisect each other.
What are all parallelograms?
This how you find the length of a square's side by using the length of the square's diagonals.
