Presentation Transcript


1. Quadrilaterals Definitions and Types

2. Your Mission, should you choose to accept it: Learn as much as you can about quadrilaterals Follow hyperlinks for extra definitions Use the button to move to the next slide Use the button to return to the previous slide Test your knowledge along the way

3. Along the way… You will acquire knowledge about: Rectangles Squares Parallelograms Rhombuses and Trapezoids Their definitions are very important to your survival in Geometry!

4. Relationships

5. Any closed plane figure with 4 segments as sides: Quadrilaterals

6. Quadrilateral Check list: There are 4 sides and Each side is a line segment and The figure is closed and All segments are in one plane

7. Quadrilaterals and Non-Quadrilaterals

8. Did you find 7? Yes or No

9. Test Your Knowledge: NOT 4 sides NOT all line segment NOT closed NOT in one plane

10. Did you choose 1 correct answer Yes or No

11. Test Your Knowledge: NOT 4 sides NOT all line segments NOT closed NOT in one plane

12. Did you choose 3 correct answers? Yes or No

13. You are on your way! There are 5 types of quadrilaterals that you will learn about: Parallelograms Rectangles Squares Rhombuses and Trapezoids

14. Watch Out… Carefully analyze the definitions Even little words count! Words like exactly one: not 2 , not 0; just 1 Or at most one: could be 0 or 1 Follow hyperlinks to clarify any unknown words. There are symbols for some of the characteristics, pay attention to these.

15. During the next lessons Repeat a previous slide if needed by using the button. Go onto the next slide by using the button Visit the Venn diagram of relationships at any time

16. Types of Quadrilaterals Parallelograms Rectangles Squares Rhombuses Trapezoids

17. Parallelogram A quadrilateral with both pairs of opposite sides parallel.

18. Parallelogram Check List Must be a Quadrilateral Both pairs of sides must be parallel

19. Choose the best answer(s)

20. Did you find 1 right answer? Yes or No

21. Choose the best answer(s)

22. Did you find 3 right answer? Yes or No

23. Rectangle A parallelogram with 4 right angles.

24. Rectangle check list Must be a parallelogram and Must have 4 right angles

25. Check out this site: Explore this applet Compare parallelograms and rectangles Click the back button when done Go to applet

26. Squares A rectangle with all 4 sides equal in length

27. Square check list: Must be a rectangle and All 4 sides equal in length

28. Rhombus A parallelogram with all 4 sides of equal length.

29. Rhombus check list: Must be a parallelogram and All 4 sides of equal length

30. Trapezoid A quadrilateral with exactly 1 pair of parallel sides.

31. Trapezoid check list: Must be a quadrilateral and Only 1 pair of parallel sides

32. Relationships

33. Check out this site Explore the gizmo! Then answer the questions provided Click the back button when finished Go to Gizmo

34. Parallel lines Lines in the same plane that do not intersect: Like a set of rail road tracks.

35. Plane A flat surface that extends without end in all directions.

36. segment or line segment Consists of any 2 distinct points (different) on a line and all the points between them:

37. Right Angle An angle whose measure is 90 degrees.

38. Quadrilateral Check list: There are 4 sides and Each side is a line segment and The figure is closed and All segments are in one plane

39. Rectangle check list Must be a parallelogram and Must have 4 right angles

40. Parallelogram Check List Must be a Quadrilateral Both pairs of sides must be parallel

41. Rhombus check list: Must be a parallelogram and Must have all sides of equal length

42. Trapezoid check list: Must be a quadrilateral and Must have only 1 pair of parallel sides

43. Square check list: Must be a rectangle and Must have all 4 sides equal in length

44. Relationships
