  1. Chapter 9 Section 9.8 Proportional Segments

  2. Triangle Proportional Thm. If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.

  3. Example: Find x 4 cm 3 cm 2 cm x

  4. Corollary If 3 parallel lines are cut by two transversals then they divide the transversal proportionally

  5. Example: Find x a || b || c a 2 in b x 14 in c 12 in

  6. Example: Find Unknown Lengths 12 m 9 m x x + 1

  7. Example: Is KM || JN 1 1.5 K M 3 2 J N

  8. Example: Is QS || PT Q 2 3 P 4 S 7 T

  9. Triangle Angle Bisector Thm. If a ray bisects an angle of a triangle it divides the opposite side into proportional segments to the other 2 sides of the triangle.

  10. Example: Find t 6 ft 12 ft t 21 ft

  11. Example: Find x and y Perimeter: 40 ft 4 6 x y
