We then used common sense to figure out the midpoint formula for segments in the coordinate plane (which will also allow us to see if diagonals share a midpoint).
HW #16: p 281-3: 1-6,11, 15-17, p 37: 3-4, 6-8.
And write up C 45 to C 48 from pp 269-70 (using notes to help you get sketches and fill-in-the-blank.
Students made sure they understood the kite and trapezoid conjectures and found their mistakes on homework over that.
There will be a quiz on Thursday-Friday over sections 1-4 of Chapter 5. Midpoint will be on the quiz. The quiz will have some true/false over C-30,32-41, and 44. The rest of the quiz will be missing angles or sides found using what you know from the conjectures. One midpoint problem.
"Test" will be Thursday-Friday next week, with 1st and 2nd having a shorter test than 6th-8th.
