  1. SETUP DIRECTIONSPlease take out Assignment Calendar, andCopy Tonight’s HWMaterials on your desk:Drill Sheet, Pencil, Foldable, Last Night’s Homework (ws 1-5)Begin your drill! (located on the front table)

  2. GEO Warm-up: 9/23 and 9/24 Name: ____________________ Date: ____________ Pd: _____ Use the following picture to answer the following questions: a) What is ? b) Find the value of x. c) Find . d) Find . 2) Remember back to last class, give the best vocabulary word describing the following angles or sides. a) and are? b) If = 108°. Find the remaining angles in the picture! 3) If RS = 3x + 1, ST = 2x - 2, and RT = 64. Find the value of x and each segment.

  3. Mastery Objective We will use geometric tools to construct perpendicular and angle bisectors. We will also review segment and angle addition problems and questions.

  4. Agenda Copy HW/Drill Last Call on Missing HW Assignments TODAY IS THE LAST DAY FOR MISSING ASSIGNMENTS ON PROGRESS REPORT #1. Perpendicular Bisector Construction Angle Bisector Construction Segment and Angle Addition Review Summary Geometry Aerobics

  5. Constructions • When it tells us to construct a figure, you MUST use a compass. A compass is a geometric tool used to construct angles, arcs, copy lines, and drawing circles.

  6. Let’s Try Some Constructions • Let’s start with PERPENDICULAR BISECTOR. • Now let’s try an ANGLE BISECTOR.

  7. Reviewing Segment and Angle Addition • Things to remember: • Step 1: Always label your picture. • Step 2: Then write an equation. • Step 3: Then solve the equation. • Step 4: Plug your values into your segment or angle lengths.

  8. Practice Problems • If DF = 48, find the value of x. Then find DE and EF.

  9. Practice Problems • If GI = 51, find the value of y. Then find GH and HI.

  10. Practice Problems • If AC = 63, find the value of z. Then find AB and BC.

  11. Practice Problems If the measure of angle POR is 120°. Find the value of y. Then find the measure of angle POQ and QOR.

  12. Practice Problems Find the value of x. Then find the measure of angle EFD and DFC.

  13. Practice Problems Find the value of x. Then find the measure of angle GJH and HJI

  14. Practice Problems • TE bisects
