Geometry – Chapter 4: Congruent Triangles October 21 – 25 Objectives: 4.1 Name congruent parts 4.1 Find congruent shapes 4.2 Prove triangles congruent by SSS 4.2 Prove triangles congruent by SAS 4.3 Prove triangles congruent by ASA 4.3 Prove triangles congruent by AAS 4.4 Prove various angles and segments congruent by CPTCT 4.5 Utilize theorems about isosceles triangles 4.6 Prove triangles congruent by HL 4.7 Prove triangles congruent by using other triangles and various methods Time Line: Monday (10/21) Tuesday (10/22) Wednesday (10/23) Chapter 4.5 Isosceles and Equilateral Triangles: apply properties, definitions, and theorems of two dimensional figures to solve problems and write proofs; proving the Isosceles Triangle Theorem and its Equilateral corollaries Chapter 4.6 Congruence in Right Triangles: apply properties, definitions, and theorems of two dimensional figures to solve problems and write proofs; proving the Hypotenuse-Leg (HL) Theorem using flow proofs and twocolumn proofs [examples of flow proofs p.231 & p.199:28] Chapter 4.7 Using Corresponding Parts of Congruent Triangles: apply properties, definitions, and theorems of two dimensional figures to solve problems and write proofs; identifying and using overlapping triangles in proofs Assignment: Read p.210213; do p.214: #1-15 and p.199:30 Assignment: Read p.217-219; do p.219: #1-11 (odds) and p.221: 16-17,19-20 Assignment: Read p.224226; do p.226: #1-18 (evens), 27-28 Vocabulary: Congruent Polygons CPCTC Legs of Isosceles Triangle Base of an Isosceles Triangle Vertex Angle of Isosceles Triangle Base Angles of an Isosceles Triangle Corollary Hypotenuse Thursday (10/24) Friday (10/25) Chapter 4 Open Book Review Triangle Congruence by ASA and AAS: apply properties, definitions, and apply properties, definitions, and theorems of two dimensional figures to solve problems, plan and write proofs Chapter 4 Test Congruent Triangles (Closed Book) Assignment: Review notes, especially definitions, properties, postulates, and theorems; Do p.233:11-39 (odds) Assignment: Write a proposal with sample diagrams of a “Rules Review Game” for definitions, properties, postulates, and theorems. The game should include the wording of each rule; an example of how to apply each rule; and rules for how to play and “win” the game
