R A Homework 1c1 Copy into your Planner Finish Example Exercises 1-4 & Mixed Exercises 1 - 4 # 1-7, 9-11, 21 & 22 Drill 1c1 #1 Solve for x: 4 + 2x + 4x = 25 CLT 6x + 4 = 25 S4 6x = 21 D6 x = 3.5 Drill 1c1 #2 Find the perimeter of the pentagon. P = 4.1 + 6.8+ 5.4+ 3.5+ 8.3 = 28.1 in Drill 1c1 #3 Name this figure. R A RA Unit: Tools of Geometry Lesson 1c1: Measuring Angles & Segments Objective: The student will use geometric tools and postulates to find measures of segments and angles. Make sure that you have copied the objective on Worksheet 1-4 Unit: Tools of Geometry Lesson 1c1: Measuring Angles & Segments Postulate 1-6: Segment Addition Postulate If three points A, B, and C are collinear and B is between A and C, then AB + BC = AC. A B C Make sure that you have copied this in your “notes” book for Section 1-4. Ruler Postulate / Segment Addition Postulate Find the length of segment AC. (AC - the length of AC) a. AC= -2 - - 5 = 3 This is like counting steps! In Geometry a length is never negative! Ruler Postulate / Segment Addition Postulate Find the length of segment CY. (CY - the length of CY) b. CY= 5 - - 2 = 7 This is like counting steps! In Geometry a length is never negative! Ruler Postulate / Segment Addition Postulate Find the length of segment AB. (AB - the length of AB) c. AB= 0 - - 5 = 5 This is like counting steps! In Geometry a length is never negative! Ruler Postulate / Segment Addition Postulate Find the length of segment BY. (BY - the length of BY) d. BY= 5 - 0 = 5 This is like counting steps! In Geometry a length is never negative! Ruler Postulate / Segment Addition Postulate Find the length of segment XA. (XA - the length of XA) e. XA= 2 - - 5 = 7 This is like counting steps! In Geometry a length is never negative! Ruler Postulate / Segment Addition Postulate Find JK if the coordinate of J is -4 and of the coordinate of K is 7 . (Count the distance from J to K) h. JK = 7 - - 4 =11 This is like counting steps! In Geometry a length is never negative! Ruler Postulate / Segment Addition Postulate Find ST if the coordinate of S is -1 and of the coordinate of T is -9 . (Count the distance from S to T) i. JK = -1 - - 9 = 8 This is like counting steps! In Geometry a length is never negative! Now finish working problems 5 – 20 & 1-4 Example Exercises 1-4 Why are you still watching the screen? Ruler Postulate / Segment Addition Postulate Find the length of AC + CY. (ADD - the lengths of AC & CY) f. AC + CY= (-2+- 7 = +10 -2)= 3 -5) (5- This is like counting steps!
