Then we practiced using and interpreting slope of sides of figures to connect to type of quadrilateral.
Students need to get their current conjectures caught up with good sketches (30-48). You should already have 42 and 43 from the similarity unit. And 31 is not necessary (pentagon sum is 540 degrees).
The quiz on Thursday-Friday is about 30 pts. It has True/False over the conjectures. It has missing angles and sides based on application of conjectures (particularly Polygon Sum). It also has an algebra problem a lot like #10 on p 167. Be sure that you can find sums of interior and exterior angles and single angles in equiangular polygons.
HW #17: p 167:1-4, 7-12, pp 275-278:1-6, 15-17.
We will begin the next block by working part of the attached sheet to practice for the quiz.
