MAFS.912.G-CO.3.11: Prove theorems about parallelograms; use theorems about parallelograms to solve problems. (Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.)
MAFS.912.G-GPE.2.4: Use coordinates to prove simple geometric theorems algebraically.
MAFS.912.G-GPE.2.7: Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula.

| Learning Targets and Learning Criteria |
|---|
- choose appropriate formula (such as distance, midpoint, or slope) to identify the geometric figure and its properties.
- prove or disprove that a figure defined by given points in the coordinate plane is a triangle, rectangle, kite, rhombus, trapezoid, square, regular polygon, etc.
- use coordinates and the appropriate formula to prove or disprove a claim about a figure.
- Use properties of parallelograms, NOT assumptions, to correctly identify figures.
- use the distance formula to compute the perimeter and area given the coordinates of vertices of a polygon like triangle, square, rectangle, kite, rhombus, trapezoid, etc.
- decompose more complex figures whose vertices are given using coordinates into familiar shapes that are easier to work with.
