  1. Warm Up Find the values of y by substituting x = 2, 3, 10 y = 3x-1 y = 4(x+3) y = 8(x+4) + x(8+x)

  2. Today’s Objective • To identify basic shapes and figures in Geometry in order to use them for future objectives. • Homework: Marking Figures Worksheet

  3. To identify basic shapes and figures in Geometry • Warm Up √ • Anticipatory Set • Marking Figures • Vocabulary • Ruler Postulate notes • Segment Addition Postulate Notes • Intersecting Lines and Planes • Gallery Walk • Closure

  4. Anticipatory Set • Where in the room do we find: • Point • Line • Plane • Segment • Ray

  5. Measurements: Congruent/Equal Segments: Bisected Segments: Marking Segments E 4 cm F G Y Z X B D H A C

  6. Warm Up • Mark up the angles and segments to show the statements J G Y Z X K M H L

  7. Today’s Objective • TSWBAT understand basic figures and postulates in Geometry in order to use them later in the course. • Homework: Pg 12 #1-19 odd

  8. To identify basic shapes and figures in Geometry • Warm Up √ • Anticipatory Set √ • Marking Figures Worksheet √ • Vocabulary • Ruler Postulate notes • Segment Addition Postulate Notes • Intersecting Lines and Planes • Gallery Walk • Closure

  9. Vocabulary • Postulate • Coordinate • Distance • Between • Congruent Segments

  10. Postulate • A rule that is accepted without any proof

  11. Name of Points A B 3 6 Coordinate of Points Coordinate • The number that corresponds to a point • Where the point is located

  12. Distance • How far apart two things are. • The absolute value of the difference of the coordinates of the point • A is at coordinate 1 • B is at coordinate 8 • The distance between A and B is: Which equals?

  13. B A C Between • When 3 points are collinear then the point in the middle is “between” the other two • B is between A and C

  14. Congruent Segments • Line segments that have the same length are congruent segments.

  15. To identify basic shapes and figures in Geometry • Warm Up √ • Anticipatory Set √ • Marking Figures Worksheet √ • Vocabulary √ • Ruler Postulate notes • Segment Addition Postulate Notes • Intersecting Lines and Planes • Gallery Walk • Closure

  16. A=0 B=3 C=5 D=10 Ruler Postulate • The points on a line can be matched one to one with the real numbers. Giving them coordinates • Using their coordinates, we can find the distance between the points

  17. To identify basic shapes and figures in Geometry • Warm Up √ • Anticipatory Set √ • Vocabulary Quiz √ • Vocabulary √ • Ruler Postulate notes √ • Segment Addition Postulate Notes • Intersecting Lines and Planes • Gallery Walk • Closure

  18. 15 20 B A C 35 A C Segment Addition Postulate • If B is between A and C, the AB + BC = AC • AB = 15 • BC = 20 • AC = 35

  19. Example of Segment Addition • If segment EG is 36 and segment EF is 21, what is segment FG? E F G
