  1. Quadrilaterals Polygons with four sides

  2. Foldable 1. Take out a piece of notebook paper and make a hot dog fold over from the right side over to the pink line.

  3. The fold crease Foldable 2. Now, divide the right hand section into 5 sections by drawing 4 evenly spaced lines. 3. Use scissors to cut along your drawn line, but ONLY to the crease!

  4. The fold crease Foldable 4. Write QUADRILATERALS down the left hand side QUADRILATERALS

  5. QUADRILATERALS The fold crease Foldable Parallelogram 5. Fold over the top cut section and write PARALLELOGRAM on the outside. 6. Reopen the fold.

  13. The last Box will be Other Quadrilaterals: Regular Trapezoids Irregular trapezoid Quadrilaterals Kites

  14. Characteristics Of Other Quadrilaterals • All trapezoids • Exactly 1 pair of parallel sides • 360 degrees • Regular Trapezoids: • Exactly 1 pair of parallel sides • 360 degrees • Consecutive angles total 180 degrees • Base angles are congruent

  15. Characteristics Of Other Quadrilaterals • All quadrilaterals • 4 sides • 360 degrees • Kites • Adjacent sides congruent • Diagonals perpendicular

  16. Types of Quadrilaterals • Parallelogram: Quadrilateral with opposite sides that are parallel and of equal length and opposite angles are equal Indicates equal sides

  17. Types of Quadrilaterals • Rectangle: Quadrilateral with two pairs of equal sides and four right angles (90 degrees) Indicates equal sides Box indicates 900 angle

  18. Types of Quadrilaterals • Rhombus: Parallelogram with four equal sides and opposite angles equal Indicates equal sides

  19. Types of Quadrilaterals • Square: Quadrilateral with four equal sides and four right angles (90 degrees) Indicates equal sides Box indicates 900 angle

  20. Types of Quadrilaterals • Trapezoid: Quadrilateral with one pair of parallel sides Parallel sides never meet.

  21. Types of Quadrilaterals • Irregular shapes: Quadrilateral with no equal sides and no equal angles

  22. Name the Quadrilaterals 1 3 2 irregular rhombus rectangle 5 6 4 parallelogram trapezoid square

  23. Interior Angles • Interior angles: An interior angle (or internal angle) is an angle formed by two sides of a simple polygon that share an endpoint • Interior angles of a quadrilateral always equal 360 degrees
