Tutorial: Quadrilateral Queries

In our polygon unit we are learning about four-sided figures called

QUADRILATERALS!


Many people were confused about why some shapes have more than one name.
Here are some tutorials to help you learn about quadrilaterals.

Tutorial #1 - What is a parallelogram?

Here is an interactive parallelogram.


Tutorial #2 - What is a rhombus?

Here is an interactive rhombus.


Tutorial #3 - What is a rectangle?

Tutorial #4 - What is a square?

  4. Dear Class,
    I love how I can rely on you to help me learn. I noticed that in my house there is a piece of plastic shaped like a rectangle. It's also a parallelogram.

  6. Dear Class,

    I think these tutorials are very useful! I can't wait to film the square tomorrow.

    You are all becoming very good public speakers!

    Great job!

  7. Dear Class,
    On my homework I noticed something that looked wrong in one of the tables about the rhombus. The characteristics of a rhombus are four equal sides and no right angles. On our class movie about the rhombus, it states that a square is also a rhombus. I looked further in a dictionary and discovered a rhombus is an oblique- angled equilateral parallelogram; any equilateral parallelogram except a square. The square is only considered a rhombus in special cases.

  8. Dear Class,

    Wow! What a great job you all did! I hope that the square post is going to be on the blog soon. I love that Kyle used his hands to show that the lines were parallel.
    I loved all of them. It helped me solve some of the problems.

    Your classmate,
    Shane F. :-)

  9. Dear class,

    Thank you very much for the geometry lesson. It has been a long time since I have had to think about an equilateral parallelogram. Keep up the great work!

  10. Dear Matthew,
    Thank you for all of your research! You said, "The square is only considered a rhombus in special cases." I wonder what those special cases are?

    I am going to find out! (Unless you beat me to it!)

    Thank you for your hard work!

  12. Dear Class,

    What are your favorite shapes; a rhombus, parallelogram, rectangle, or a square? Atleast one person can
    answer me.


    Yours truely,

  13. Dear Lexi,

    You asked which shape is my favorite. I love the square.

    It is my favorite quadrilateral because I like right angles. In addition, it has four lines of symmetry, and I think that is interesting. Finally, I like that when you fold it diagonally, it makes an isosceles right triangle.


    Thanks for asking! I hope other readers will reply.

    Which is your favorite quadrilateral?

    Sincerely,
    Mrs. Yollis

  14. Dear Class,
    Thanks, now I know what a parallelogram, a rhombus, a square, and a rectangle is!

  15. Dear Lexi,

    My favorite shape is a rectangle, because it has 4 right angles.

    What is your favorite shape?

    Thanks,
    Taylor S. :D

  16. Dear Mrs. Yollis,

    I love how you found that square! Was it hard looking all over the internet for it?

    :D Thanks,

  17. Dear Class,

    My favorite tutorial was about the rectangle because it reminds me of my hockey stick's blade which is kind of similar to a rectangle.

    Thanks for the help!

  18. Dear class,

    Today during math homework I noticed that they asked a quadrilateral question I needed a tiny up-date on quadrilaterals because we have not done quadrilaterals in a few months.

    I used it on #3. I got stuck a little on #8 (it was about perimeter) maybe we should do a post about perimeter!

    Love,
    Bethany :)
