Characteristics and Properties

A1. Use proportional reasoning to describe and express relationships between parts and attributes of similar and congruent figures.

A2. Determine sufficient (not necessarily minimal) properties that define a specific two-dimensional figure or three-dimensional object. For example:
a. Determine when one set of figures is a subset of another; e.g., all squares are rectangles.
b. Develop a set of properties that eliminates all but the desired figure; e.g., only squares are quadrilaterals with all sides congruent and all angles congruent.

A3. Use and demonstrate understanding of the properties of triangles.
For example:
a. Use Pythagorean Theorem to solve problems involving right
b. Use triangle angle sum relationships to solve problems.
