  1. 1.5 Segment and Angle Bisectors POD: How can you divide a segment or angle into two equal parts? 1. Work with a partner 2. You will need a ruler and protractor Follow these directions: Do each on a separate piece of paper!

  2. 1.5 Segment and Angle Bisectors Vocab: Midpoint: Bisect: Segment Bisector: Angle Bisector: Construction:

  3. 1.5 Segment and Angle Bisectors Let’s Bisect a Segment!!!

  4. 1.5 Segment and Angle Bisectors Let’s Bisect an Angle!!!

  5. 1.5 Segment and Angle Bisectors Finding the Midpoint of 2 coordinates: THE MIDPOINT FORMULA

  6. 1.5 Segment and Angle Bisectors Example 1: Finding the Midpoint Find the coordinates of the midpoint of AB with endpoints at A(-2, 3) and B(5, -2).

  7. 1.5 Segment and Angle Bisectors Example 2: Finding the Endpoint The midpoint of RP is M(2, 4). One endpoint is at R(-1, 7). Find the coordinates of P.

  8. 1.5 Segment and Angle Bisectors Example 3: Dividing an Angle in Half The ray FH bisects the angle <EFG. Given that m<EFG = 120˚, what are the measures of <EFH and <HFG?

  9. 1.5 Segment and Angle Bisectors Example 5: Finding the Measure of an Angle RQ bisects <PRS. The measures of the two congruent angles are (x + 40)˚ and (3x -20)˚. Solve for x.

  10. 1.5 Segment and Angle Bisectors Homework: 1.5 Practice B all odds!!!!!
