Today we studied similarity, particularly of triangles. This is Chapter Seven in the textbook. There are some topics touched only lightly in class. Please be sure to read the review page assignments!
Do the problem sets in the handouts. Keep reviewing vocabulary, theorems and postulates.
Be sure to check answers for textbook problems in the back of the book as you go along!

Chapter Seven
Review
p464 Definition
p475 Theorem - particularly pay attention to the difference between perimeter ratios and area ratios
p478-9 Golden rectangles and the golden ratio- we didn't cover this but it is useful to be familiar with
p 487 - AA Similarity (Triangle SImilarity I in class focused on this)
p 492-3 SAS and SSS Similarity (Focus of Triangle Similarity II)
p 496-8 Dilations and definitions (Focus of Scaling and Dilation)
p 502 Midsegments (we explored this in the Special Lines in Triangles lesson)
p 512-3 Trigonometric ratios (from Basic Trig Ratios)
p 518-9 Angles of Elevation and Depression from Applications of Trig lesson.
