Students re-capped prior knowledge with a warm-up about the basics of similarity.
Many students have not taken the last test. Please come during advisory tomorrow. Also come if you know you need to do a re-test.
After discussion of the homework page and learning about the midsegment of a triangle and how it relates to the larger triangle, the homework was collected for a grade.
We looked at a mathopenref demonstration of dilation and center of dilation and scale factor. Then we tried two problems that worked similarly.
At the end of class HW #12 (dilations) was handed out, followed by a Geogebra demonstration of Triangle Similarity Shortcuts.
Download HW #12 and/or the in-class dilation activity below.
THERE WILL BE A QUIZ FRIDAY OVER THE BASICS OF SIMILARITY THAT WE HAVE LEARNED SO FAR. THIS WILL INCLUDE DILATIONS.
