1. Find the Distance and Midpoint between the two points (-12, 6) and (-4, -3)

2. 4.2 Triangle Congruence by SSS and SAS

3. Learning Target
I can prove two triangles congruent using the SAS and SSS postulates

4. Side-Side-Side (SSS) Postulate : If three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

5. Side-Angle-Side (SAS) Postulate: If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent

6. Examples of Both

7. From your 4-2 worksheet

8. Lets do 1-9 on the 4-2 worksheet

9. Proving #14 and #15 together

10. RECAP:
Do you know what SSS and SAS means?
Can you identify two triangles congruent with the SSS and SAS Postulates?
Can you provide Reasoning in a Proof?
