Ohio Content Standards:

• Formally define geometric

figures.

Page 4: Lesson 1-6

Ohio Content Standards:

• Use coordinate geometry to represent and examine the properties of geometric

figures.

Page 5: Lesson 1-6

Ohio Content Standards:

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