Hints for the Similarity Review problems

First, in problem 5, the median should be AD (not AB). Secondly, also in problem 5, it may be helpful to draw a line that through D that is parallel to BQ.

Remember that you do not always need to prove some triangles are similar to get the ratios you need. Parallel lines and angle bisectors also give you useful ratios.

Topic List for the MidYear Exam

You can download the topic list here. Remember that the table of contents in the book also serves as a topic list.

Polyhedra

Polyhedra are 3D solids made of polygons. We are focussing particularly on polyhedra made of regular polygons. You should be able to determine information about them without actually building and counting. Every day there is a handout so the homework is to work your way through the packet.

1/12 Half Day B A G F (no class)
1/13 Archimedean Solids (the rest of the semi-regular polyhedra)

Tessellations

Tessellations are a fun way to put together what we have learned about transformations with triangles and quadrilaterals (among other shapes).
