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 segments1. vertex = each point where two sides meet2. n-gon = polygon w/ “n” sides3. decagon = 10-sided polygon
Guided Learning:1. Review divisibility rules (slide 2)2. Review EXAMPLES A. and B. -- How did you decide 610 was not divisible by 3?
Introduction: Quick Review Objective: learn how to classify triangles and solve problems involving angle measures of triangles Vocabulary: • acute triangle = contains only acute angles1. obtuse triangle = contains only one obtuse angle• right triangle = contains only one right angle1. equilateral triangle = three congruent sides2. isosceles triangle = exactly two congruent sides• scalene triangle = no congruent sides
Guided Learning:1. Review divisibility rules (slide 2)• Review EXAMPLES A. and B. -- How did you decide 610 was not divisible by 3?
Introduction: Quick Review Objective: learn how to use the strategy “find a pattern” to solve problems Vocabulary: 1. regular polygon = polygon which all sides and angles are congruent
Introduction:1. Quick Review: Complete on your white board2. Objective: Learn how to identify and draw parts of circles3. 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!
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
