In today’s class we corrected the homework and then we started the lesson 11-8 Congruent and Similar Solids. In this lesson we also reviewed things from chapter 7 which talks about similar polygons so; we just applied the similar and proportional principles to solids. As an example if in two similar spheres one radius is 5 times bigger than the other radius, then the area will e 25 times bigger and the volume 125 time bigger.
Lengths--- Areas--- Volumes
a/b ---a squared/b squared--- a cubed/ b cubed
Schedule:
