1. Overlapping Triangles Lesson 3.5

2. What are overlapping triangles? A There are two triangles that overlap inside the larger triangle. Outline the overlapping triangles with different colored pencils or markers. D E C B

3. Where are the overlapping triangles? Outline the overlapping triangles with different colored pencils or markers.

4. Overlapping triangles can be matched by CPCTC. Given: AB  DC AC  DB Prove △ABC  △DCB D A E B C

5. Statement Reason • AB  DC • AC  DB • BC  BC • ABC  DCB • Given • Given • Reflexive Property • SSS

6. Given: <1 = <3 <1 comp <2 <3 comp <4 Conclusion: AB = CD D A E 3 1 2 4 B C

7. Statement Reason • Given • Given • Given • Comps of s are . • Addition Prop. • Reflexive Prop. • ASA • CPCTC • 1. 1 is comp to 2. • 2. 3 is comp to 4. • 1  3 • 2  4 • ABC  DCB • BC  BC • ABC  DCB • AB  CD
