Today, Monday, we discussed the POW, Presentation Perplexers, and we acted out a room full of liars and truth-tellers to solve a logic puzzle. We also discussed two important terms in geometry, "similar" and "scale factor."
Polygons are similar if:
· their corresponding angles are equal
· the scale factor between their corresponding sides is the same
The scale factor is the ratio of the side of one polygon to the side of second similar polygon. It tells how many times longer (or shorter) the sides of the image are than the sides of the original figure. Class notes may be downloaded here.
We discussed the Math Reflections 2 handout, which can be downloaded here. If you did not finish answering questions 1-4, please complete them for tomorrow.
Due tomorrow, Tuesday, November 17.
