  1. CP Geo: Chapter 3 3.2 Prop of Special Quads Obj: ________________________ ____________________________

  2. Special Quad • 4 sided figure with special properties

  3. Trapezoid • A quad with 1 and only 1 pair of // sides

  4. Parallelogram • A quad with 2 pairs of parallel sides

  5. Rhombus • A quad with 4 congruent sides

  6. Rectangle • A quad with 4 rt angles

  7. Square • A quad with 4 congruent sides and 4 rt angles

  8. Terms to Know • Diagonal: segment that joins 2 nonconsecutive vertices • Bisector: runs through the midpt of a segment • Perpendicular: intersects at a 90 degree angle

  9. Special Prop of Quads • Parallelogram • Opp sides are // • Opp sides are congruent • Opp angles are congruent • Diagonals bisect each other • Consecutive angles are supp

  10. Rhombus • A rhombus is also a __________________ So it has all of its prop. plus • All sides are congruent • Diagonals are perp • Diagonals bisect 2 <‘s

  11. Rectangle: • A rectangle is also a __________________, so it has all of its properties plus • All angles are rt <‘s • Diagonals are congruent

  12. Square • A square is also a __________________, a ______________, and a ________________,

  13. Example Given parallelogram ABCD • Find • AB • AE • <ABC • <BCD A B E 50 D C 1 in 3 in.

  14. Example • Given Rhombus FGHI F G H I • Find • FG • M<GHI • M<FGH • M<FJG 30 12
