1. Minimum Measurement Congruent Triangles

2. 43210 In addition to 3, student is able to teach others how to apply properties of transformations. Apply properties of transformations to perform and explain sequences of transformations and prove figures are congruent. Apply properties of transformations to perform sequences of transformation. With help, apply properties of transformations to perform sequences of transformation. Even with help, I am unable to apply properties of transformations. Learning Goal 2(8.G.A.2, 8.G.A.3): Apply properties of transformations to perform and explain sequences of transformations and prove figures are congruent.

3. What does “corresponding” mean? Corresponding sides or angles means that the side or angle appears in the same place in the other figure. How do you visually recognize the corresponding pairs of sides? Which side of ΔPQR should match segment AC? Explain how you know. Which angle is the largest angle in ΔABC? Where is the corresponding angle in ΔPQR located?

4. Is there enough information? Can you be sure that two triangles are congruent if you know that there is only one pair of corresponding sides are congruent? Work with a partner to come up with an explanation to prove this is true or prove it is not. Not enough information:

5. Is there enough information? Can you be sure that two triangles are congruent if you know that there is only one pair of corresponding angles are congruent? Work with a partner to come up with an explanation to prove this is true or prove it is not. Not enough information:

6. Is there enough information? Can you be sure that two triangles are congruent if you know that there is only two pairs of corresponding sides are congruent? Work with a partner to come up with an explanation to prove this is true or prove it is not. Not enough information:

7. Is there enough information? Can you be sure that two triangles are congruent if you know that there is only two pairs of corresponding angles are congruent? Work with a partner to come up with an explanation to prove this is true or prove it is not. Not enough information:

8. Is there enough information? Can you be sure that two triangles are congruent if you know that there is one pair of corresponding angles that are congruent and one pair of corresponding sides that are congruent? Work with a partner to come up with an explanation to prove this is true or prove it is not. Not enough information:

9. Use Labsheet 2.3 to complete the activity.
