  1. Warm Up Add five more straight lines to make 10.

  2. Agenda • Warm-Up • Questions on HW • Grade HW • Notes • Homework

  3. ANGLES

  4. ANGLES THE SAME INITIAL POINT VERTEX TWO DIFFERENT RAYS SIDES

  5. Naming Angles A 1 B C

  6. OR OR M H A T Naming Angles 1 2

  7. Interior = Inside A B C Exterior = Outside

  8. ANGLE MEASURE

  9. ACUTE ANGLES = Greater than 0 and less than 90 RIGHT ANGLES = Measure exactly 90 OBTUSE ANGLES = Greater than 90 and less than 180 STRAIGHT ANGLES = Measure exactly 180

  10. PROTRACTOR

  11. How To Measure An Angle

  12. 132 1 76 2

  13. 105 3 14 4

  14. How to draw an angle * Start off by drawing a ray. * Line up the vertex to the hole and the side of the angle with the line next to the hole * Follow your ray to zero and then over to the angle measure. Make a mark and then connect it to the vertex.
