Started assessment. No new hw.
Tuesday/Wednesday
Finished assessment. Proved quadrilaterals on the coordinate plane. Started eLab present project.
Homework
start working on your present project: prompt
Watch and take notes on this video: link
Got assessments back and went over common mistakes briefly. Applied the idea of similarity and the fact side lengths are proportional to each other to set up and solve proportions (using cross multiplication) to find missing lengths. Determined whether or not given triangle pairs were similar using the 3 rules specified in the video above. Worked on our design projects some more.
