Objective: The students will discover the properties of interior and exterior angles of polygons Activity: Students will be given different shapes and a protractor. They will explore the interior and exterior angles to come up with rules. 3)Classwork: Interior & Exterior Angles W.S. Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment's endpoints. Know precise definitions of circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc. Day 106 1) Classwork: Hang Drywall on Ceilings 2) Classwork: Hang Drywall on Walls Day 107 1)Lesson: Midpoints and Midsegments of Triangles & Trapezoids Objective: The students will apply the midsegments of triangles and trapezoids in problem solving situations 2) Activity: The students will explore the angles and midsegments of a trapezoidal bay window 3) Classwork: Midsegments W.S. 4) Lesson: Geometric Constructions Objective: The students will perform the construction of an angle and segment bisector as well as copying an angle and segment
