  2. Ohio Content Standards:

  3. Ohio Content Standards: • Formally define geometric figures.

  4. Ohio Content Standards: • Use coordinate geometry to represent and examine the properties of geometric figures.

  5. Ohio Content Standards: • Make and test conjectures about characteristics and properties (e.g., sides, angles, symmetry) of two-dimensional figures and three-dimensional objects.
