Quadrilateral Chart (1st Block)
Parallelograms (2nd Block )
a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or right angles).
A rhombus is a parallelogram with four equal sides, like a square. Unlike a square, however, a rhombus has opposite and equal acute angles, and opposite equal obtuse angles.
a rectangle is any quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°). It can also be defined as a parallelogram containing a right angle.

Properties of a parallelogram (4th block)
There are six important properties of parallelograms to know:
1. Opposite sides are congruent (AB = DC).
2. Opposite angels are congruent (D = B).
3. Consecutive angles are supplementary (A + D = 180°).
4. If one angle is right, then all angles are right.
5. The diagonals of a parallelogram bisect each other.
6. Each diagonal of a parallelogram separates it into two congruent triangles.
Trapezoid and Isosceles Trapezoid (5th Block)
A trapezoid isosceles is a trapezoid with legs that are congruent
- the bases are parallel by definition
- each lower base angle is supplementary to the upper base angle on the same side.
Isosceles Trapezoid Properties:
- The legs are congruent by definition.
- The lower base angles are congruent.
- The upper base angles are congruent.
- Any lower base angle is supplementary to any upper base angle.
- The diagonals are congruent.
