Geometry # 7 Lines, Angles, and Geometry Day 1 2 3 4 Lesson Introduction to geometry 7.1 Description Define, ray, line segment, line, point and angles. Resources Notes on Board Homework none Key Math Learnings -board notes - examples on board p. 274 1- 8 Textbook, large triangle, board notes p. 281 1-4 Textbook Mr. T’s Math Resources p. 287 1- 3 5-7 9-13 Textbook Mr. T’s Math Resources p. 292 Angle Properties of Intersecting Lines 1. Two angles whose sum is 90º 7.2 Angles In a Triangle Key Math Learning 7.3 Key Math Learning Angle Properties of Parallel Lines are complementary. 2. Two angles whose sum is 180º are supplementary. 3. For any intersecting lines, the opposite angles are equal. The sum of the angles in any triangle is 180º. When a transversal intersects parallel lines: • alternate angles are equal • corresponding angles are equal • interior angles are supplementary Quiz on relationship between R and D and C and pi 5 Mid Unit Review 6 Quiz 7 7.4 Constructing a Bisector Key Math Learning 7.5 Constructing Angles Key Math Learning 8 9 Quiz # 2 10 Unit Review 11 Unit Test 12 SAT, OAT, CAT, Triangles, Angle properties of parallel lines p. 296 The properties of a rhombus can be used to construct the perpendicular bisector of a line segment, and the bisector of an angle. The constructions of 60º and 90º angles can be used to draw other angles. Textbook Mr. T’s Math Resources p. 302 1-8 p. 310 -315 13
