Chapter 5 Agenda The end of the semester exam will follow this chapter! Happy Friday! November 1st, 2013 • Warm Up: Review of circumcenters and incenters! • Class work: Page 329 Exercises 9-31 odd, 41, 48, 55-58 all, 60 • Homework: watch 5-2 video. Focus ?’s: – Define Median of a triangle, Centroid of a triangle, and the Centroid Theorem. Give an example of how to find side lengths using the Centroid Theorem. – Define Altitude of a triangle and explain how it relates to the Orthocenter of a triangle. • Copy the Table on page 339 in your book to keep all of your new theorems straight Monday, November 4th, 2013 • 5-2 Warm Up: p334 Median and Altitude Constructions • Correct 5-1 class work • 5-2 class work: Page 340 Ex 6-10 even, 13, 1517 all, 20, 25, 27, 28, 37,44-47 all, 51 • Homework: Khan Academy practice, study for quiz on 5-1 & 5-2 TOMORROW!!! November 5th, 2013 • Warm up: 5-1 / 5-2 Quiz • Class work: Watch 5-3 video. Focus: – Define and give an example of the Exterior Angle Inequality – Explain angle / side inequalities and how you can use the relationships to order side lengths or angle measures from greatest to least. November 6th, 2013 • 5-3 Warm Up: Discussion with old school visual • Class work: Page 348 Exercises 9-21 (multiples of 3), 23, 24-36 (multiples of 3), 39, 46, 49-52, 55 • Homework: (skip 5-4) Watch 5-5 videos, answer focus questions – What is the Triangle Inequality Theorem? – How do we tell if 3 given side lengths will form a triangle? – If we know 2 of the 3 side lengths of a triangle, how can we find the range of possible lengths for the third side? For Review – Exterior Angle Thm What angles are greater than the blue angle? What angle(s) less than angle 4? Write the sides from greatest to smallest Write sides from smallest to largest Write angles from least to greatest measure Write angles from greatest to least measure From your notes: Example Will these side lengths form a triangle? 3, 6, 10 Will these side lengths form a triangle? 4, 6, 11 Will these side lengths form a triangle? 1, 12, 5 What is the range of possible 3rd side length? 23 and 9 What is the range of possible 3rd side length? 10 and 40 What is the range of possible 3rd side length? 33 and 7 November 7th, 2013 • Class work: p367 Ex 6, 9, 12, 15, 27, 30, 31, 39, 49-52, 56, 59 • Homework: study for quiz on 5-3 & 5-5 by completing practice quiz on ConnectED!!
