6

CHAPTER 10 VOCAB ORGANIZER Do you have the first 6 blank lines filled out? Use your 10.0 Homework

7

Lines in a plane that share a point. Lines that lie in the same plane but never intersect. Lines that DO NOT coexist in the same plane. Lines that coexist in the same plane. 2 lines that occupy the same space They are theSAME LINES! May or may not intersect.

8

Page 68-69 of your INB find x: 2 + 3x 62 Angle Cards & Unit 10 Vocab Organizer Make a POCKET PAGE. Get into your Groups

9

CUT OUT Your ANGLE PAIR CARDS

12

VERTICAL ANGLES

13

CHAPTER 10 VOCAB ORGANIZER Now fill out the next 6 blank lines.

14

ANGLES Opposite angles made by two intersecting lines CHAPTER 10 VOCAB ORGANIZER

15

ADJACENT ANGLES

17

ANGLES Side-by-side angles They share a side Opposite angles made by two intersecting lines CHAPTER 10 VOCAB ORGANIZER

18

ANGLES Side-by-side angles They share a side 2 angles whose sum is 180° Opposite angles made by two intersecting lines 2 angles whose sum is 90° 2 angles that form a line. Angles with the same measure. CHAPTER 10 VOCAB ORGANIZER

20

ANGLE PAIR CARDS FILL IN THE INFORMATION a = b Angles add up to 90° a + b = 90 Angles add up to 180 ° a + b = 180

22

EQUATION CARDS SET UP THE EQUATION AND SOLVE FOR X 19 = 3x -2 +2 + 2 21= 3x 3 3 7 = x 19 = 3x -2 2x + 5 + 3x + 15 = 90 5x + 20 = 90 – 20 – 20 5x = 70 5 5 x = 14 52 + 4x – 8 = 180 44 + 4x = 180 -44 – 44 4x = 136 4 4 x = 34

23

Day 1 – Integer operations, PEMDAS, evaluating 10.1 Angle Relationships find x: 2 + 3x Number 21 on your Homework 2 + 3x = 62 -2 – 2 3x = 60 3 3 x = 20 2 + 3x = 62
