We discussed the area formulas on p. 382 & 383, including Heron's area formula for triangles and the cool formula for the area of a triangle by its inscribed circle and perimeter... We then looked at our solids and some area and volume formulas.

 * Finish problem packet from class

=Tuesday, April 2nd, 2013= We began by correcting the Unit 6 test. We then investigated areas: In groups, we found the area of a regular hexagon with a side length of 6.2 cm. This led to a neat area formula with something called the apothem.
 * 1) Log into Khan Academy and add obrienbluester@gmail.com as a coach.

=Wednesday, March 27th, 2013= We began by going to the online Grade Calculator (make a copy for yourself (File- Make a copy...) and play with it). We then corrected the quiz and went over IW questions before taking a look at the final two sections of Chapter 6: locus and concurrence of lines. We reviewed the appropriate theorems and learned the mnemonic Many Cute People Believe Colorful Apples Bake In Airy Ovens. Questions on these two sections will be extra credit, but that's a great way to offset careless errors!!!

=Week of March 19th, 2013= Due to the snow day, Tuesday's work bumped to Thursday.

Mr. O'Brien is out this week. Your sub Mr. Wheelis will help you out- he loves geometry! You may also email questions directly to Mr. O'B (link on left).

Tuesday
Begin by making sure that you've checked your Unit 6 quiz and reading notes sheet using the solutions posted with IW #5 below. Got questions on these or IW #5? Ask Mr. Wheelis...

Spend the remainder of class working on the IW #6 sheets (answers posted below). Work from the back of the packet (9-7) to the front, as you might not have time to do all the problems in the hour dedicated to IW outside of class. Some problems involve the quadratic formula.

The questions on the quiz on Thursday will be taken directly from these four pages. You will not be able to use IW #6 during Thursday’s quiz (to avoid copying of answers without understanding).

__IW #6__:
 * Spend an hour on the packet from class (solutions here )

Log into the Khan Academy and do this these three inscribed angle exercise sets: angle side on the diameter, angle sides enclosing the diameter , and angle sides outside the diameter. Before you do each problem set, watch the set of hints for each type; they prove that powerful Theorem 6.1.2. After our circle investigation, we corrected the Unit 5 test. We reviewed the section 6.1 theorems and went over the IW.

=Friday, February 15th, 2013= We began class by going over a special right triangle problem from the IW (if you are having trouble with special right triangles, this video might help!). We then investigated the neat theorem about how a triangle's angle bisector splits the side opposite it proportionally to the two sides that make it up. We proved the theorem and then took the quiz. We spent the remainder of class with this investigation:
 * 1) Construct a triangle in Geogebra and a point anywhere on its interior.
 * 2) Extend a ray from each vertex through the point on the interior and mark the points where the rays intersect each side.
 * 3) Starting at one vertex, label the six segments that the triangle sides are divided into with the names a, b, c, d, e, and f. Find the ratio of a/b, c/d, and e/f and then multiply these ratios together. Surprised?!?
 * 4) Email your file to me.
