And it's a wrap! We are wrapping up the circle unit today. 0B is actually doing the first part of the test. Most of 6th period was gone for PSAT testing.
Our warm-up: problems over unit circle to find degrees, radians, and coordinates for a specific location on the circle, practice with similar triangles formed by "the bowtie", and practice with partial area. By today, all students should know that radians are just a measure of arc length divided by radius for any arc on any circle. For practical purposes, I have taught that radians are arc length from standard position on a unit circle. It is another form of angle measure that will be used frequently in trigonometry.
The unit review was passed out for all classes. Answers are in the next post down. I am reposting the assignment on an attachment here so that you do not have to scroll down to look for it.
We previewed solids, what is and is not a polyhedron, prism, pyramid, cylinder, cone, sphere or hemisphere. Vocabulary will be assigned on your test day, due by the next class.
I will have a study session Friday morning at 8 am.
STUDY YOUR GEOMETRIC TRUTH!! You will have fill-in-the-blank straight from the conjectures and vocabulary multiple choice similar to the matching on p 475 (answers on next post).
