Today in class we worked on beginning to wrestle with the idea of lots of different properties of different quadrilaterals.
There are several attachments below that might be helpful.
In 0B, we spent time writing up conjectures and definitions to date in the unit. On A day, the entries for Geometric Truth were a handout to be copied and completed outside of class. PLEASE DO NOT JUST GLUE THE HANDOUT INTO YOUR GEOMETRIC TRUTH. You need to write up these entries and make them match the style of what you have already done. I will be checking to see that you have completed these.
We did a fill-in-the-blank proof of two of our kite properties:
Then we looked at a sketch of a kite with its diagonals and had partner discussions to explain why the diagonals are congruent and the diagonal connecting the vertex angles perpendicular bisects the other diagonal.
Then we took notes while answering questions and making observations about trapezoids, isosceles trapezoids, and their properties. These are attached below.
HW #13: p 271: 17 (mini-proof), p 278-9: 3-4, 6-9, 20, p 307: 6-7.
(0B is slightly different, add p 270:11 and take out #8 on p 279)
And get those Geometric Truth entries done!
Quiz 5.1 -3 will be on Fri-Mon, March 6, 9 for 30 pts. A topic list will be on the next post.

We did a fill-in-the-blank proof of two of our kite properties:
- The non-vertex angles of a kite are congruent.
- The diagonal connecting the vertex angles of a kite is an angle bisector.
