Geometry: Chapter 6 6.4: Rhombuses, Rectangles, and Squares Obj: _____________________________ _________________________________
Special Quad • 4 sided figure with special properties
Rhombus • A parallelogram with all sides congruent
Rectangle • A parallelogram with all angles congruent
Square • A parallelogram with all angles and sides congruent
practice • Complete with Always, Sometimes or Never • 1) Is a rectangle a square? Is a square a rectangle? • If a rhombus a parallelogram? Is a parallelogram a rhombus?
Parallelogram • Opp sides // • Opp sides congruent • Opp <‘s congruent • Diagonals bisect each other • Consecutive angles are supp.
Rhombus • A rhombus is also a ___________________ so it has of their properties plus: parallelogram • All sides are congruent • Diagonals are perpendicular • Diagonals bisect the angles
Rectangle • A rectangle is also a _______________ parallelogram • All angles are congruent • Diagonals are congruent
Square • A square is also a ____________, a__________, and a______________ parallelogram rectangle rhombus So it has all of their properties
Given parallelogram ABCD, find: AB A B • AE • <ABC • <BCD
Given Rhombus FGHI, find: • FG • M<GHI • M<FGH • M<FJG
