1 16.1 Polygons p. 354 Introduction: Quick Review Objective: to name and classify polygons Vocabulary: polygon = closed plane figure w/ straight sides that are connected line segments vertex = each point where two sides meet n-gon = polygon w/ “n” sides decagon = 10-sided polygon Guided Learning: Review divisibility rules (slide 2) Review EXAMPLES A. and B. -- How did you decide 610 was not divisible by 3? http://www.hbschool.com/glossary/math2/index6.html

2 16.2 Triangles p. 356 Introduction: Quick Review Objective: learn how to classify triangles and solve problems involving angle measures of triangles Vocabulary: acute triangle = contains only acute angles obtuse triangle = contains only one obtuse angle right triangle = contains only one right angle equilateral triangle = three congruent sides isosceles triangle = exactly two congruent sides scalene triangle = no congruent sides Guided Learning: Review divisibility rules (slide 2) Review EXAMPLES A. and B. -- How did you decide 610 was not divisible by 3? http://www.hbschool.com/glossary/math2/index6.html http://www.bbc.co.uk/schools/ks2bitesize/maths/shape_space/sh apes/play.shtml http://www.mathwarehouse.com/geometry/triangles/interact ive-triangle.htm http://jmathpage.com/JIMSGeometrypage.html

3 16.3 Find a Pattern p. 360 Introduction: Quick Review Objective: learn how to use the strategy “find a pattern” to solve problems Vocabulary: regular polygon = polygon which all sides and angles are congruent http://www.hbschool.com/glossary/math2/index6.html

4 16.4 Quadrilaterals p. 362 Introduction: Quick Review Objective: learn how to identify, classify, and compare quadrilaterals http://www.hbschool.com/glossary/math2/index6.html http://jmathpage.com/JIMSGeometrypage.html

5 16.5 Draw Plane Figures p. 366 Introduction: 1. Quick Review Objective: learn how to draw plane geometric figures Square Dot Geoboard Isometric Dot Paper Square Dot Paper Isometric Dot Geoboard

6 16.6 Circles p. 368 Introduction: 1. Quick Review: Complete on your white board 2. Objective: Learn how to identify and draw parts of circles 3. Warm-Up: *Draw a dot on your white board, label it “O”. Next, draw a circle around the center dot you just drew. *Draw a radius and label it “radius” - someone explain how you did it! *Draw a diameter and label it “diameter” - someone explain how you did it! *Draw a chord and label it “chord” - someone explain how you did it!

7 16.6 Circles continued... Vocabulary: radius - line segment with one endpoint at the center of a circle and the other endpoint on the circle diameter - line segment passing through the center of a circle and has both endpoints on the circle chord - line segment with its endpoints on a circle Harcourt Math Glossary
