1. Lesson 4-3 Congruent Triangles

2. Ohio Content Standards:

3. Describe and apply the properties of similar and congruent figures; and justify conjectures involving similarity and congruence.

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

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

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.

7. Ohio Content Standards: Represent and analyze shapes using coordinate geometry; e.g., given three vertices and the type of quadrilateral, find the coordinates of the fourth vertex.

8. Ohio Content Standards: Represent and model transformations in a coordinate plane and describe the results.
