D & G blocks: reviewed concepts from chapters 7.5 & 8.1 for a QUIZ TOMORROW, then worked out side length relationships for isosceles right triangles (or 45-45-90 triangles), involving multiplying or dividing by the square root of 2 (and rationalizing the denominator, when necessary).
Homework: page 503, #7-14, #22, 27, 28, 35, 38 (D block dropped today)
******************** G block: Reviewed the Pythagorean theorem and explored how it can be used to calculate missing side lengths of right triangles, and also determine whether a triangle is right, acute or obtuse. Homework: page 495, #7-21, #27-32, and #39-42 D block: Reviewed the Pythagorean theorem and explored how it can be used to calculate missing side lengths of right triangles, and also determine whether a triangle is right, acute or obtuse.
Homework: page 495, #7-21, #27-32, and #39-42 ******************** G block: Warmed up with geometric mean proportions, then covered chapter 7.5 "Proportions in Triangles" (first, a triangle's sides are split proportionally when they're intersected by a parallel segment; second, an angle bisector splits a triangle into proportional segments). Homework: page 475, #9-12, #15-22, #33-35 D block: Reviewed geometric mean proportions and took a quiz on chapter 6.4.
No homework assigned - enjoy your vacation! ******************** G block: Reviewed geometric mean proportions and took a quiz on chapter 6.4. No homework assigned - enjoy your vacation! D block: reviewed geometric mean proportions in similar right triangles for last time before Friday's QUIZ, and then learned about proportionality in triangles that are divided by either a parallel segment of an angle bisector.
Homework: page 475, #9-12, 15-22, 33-35 (and study for quiz) ******************** (G block dropped today) D & G blocks: We continued to practice setting up and solving geometric mean proportions to find missing side lengths in similar right triangles (and simplifying radicals, where necessary). There will be a quiz on these topics (just chapter 7.4 - "banana & pear" relationships) on FRIDAY. Homework: Right Triangle Similarity (and geometric mean proportions) handout.
