(Unit 8) PP#2 - Coordinate Geometry Poster Project (& more inside)

This is a group project that is an extension of #20 on the Unit 7 Assessment.

The problem reads below:

Ms. Judy connected the midpoints of a square, and she made another square whose area was half the amount of the original square. She then made the following conjecture: “If I connect the midpoints of any unique quadrilateral, I will always make another version of that unique quadrilateral that has half its area.” Is she correct? Demonstrate with the other unique quadrilaterals (rectangle, parallelogram, kite, & trapezoid) and determine if both parts of her statement are true. Explain which parts are/are not and why. (CS 1.0, 3.0, 7.0, 10.0; CC 2, 3, 5, 6, 7, 8)

All of the directions are on the worksheet. The point was to not only use coordinate geometry purposefully, but work in groups appropriately (delegate tasks where everybody has a part to expedite the process). In the end, you are able to respond to Ms. Judy's conjecture with the work that you show.

This acts both as a response to problem #20 on the Unit 7 Assessment and a group classwork assignment.

I have now recorded three lecture videos which delve into the matter of coordinate geometry. It is your obligation to get your understanding by any possible means, so I suggest you take some time out of your day to brush up on anything regarding coordinate geometry in the following videos:
