Today we continued our work on lines and transversals. We are trying to get to the point where we accurately deal with three ideas:
1) Name angle pairs by location. Know that angle pairs that do not share a transversal do not have a name. 2) Know when angle pairs are congruent or supplementary (if the transversal crosses parallel lines).
3) Know that when the transversal does not cross parallel lines, the angle pairs are not congruent. But if I can explain another reason why they are congruent, then I can show that lines crossed are parallel.
There is a quiz the next time we meet. It is 24 points.
Study Geometric Truth - Conjectures 1,2,3, and 4 and definitions of angle pairs by good sketches.
Study HW #9 - 10. Do worksheet hand-out (HW #11).
Are these lines parallel? Explain why by identifying angle pairs that are congruent that would cause the lines to be parallel.
Identify angle pairs in sketches with no parallel lines.
What angles have to be congruent for these lines to be parallel?
One algebra problem like HW #10-11. Explain why you can set equal or add to 180.
Missing angles in a sketch.
Today we did three different activities attached below that could be helpful.
Geometric Truth should be caught up through C-4, including definition of transversal.
Attached are the angle pairs practice, the constructed response, and current Geometric Truth as well as the homework worksheet.
