Section 10.4
There are 3 formulas that you need to be able to use.

Area of a triangle: A = 1/2 bh; Area of a trapezoid:  A = 1/2h (b + c) where b and c are the measures of the bases.
Area of a rhombus:  A = 1/2 product of the measures of the diagonals.

Here is a construction that we did in class today.  We wanted to find the center of the circle:   http://www.mathopenref.com/constcirclecenter.html

Here are the notes from class today. 9.4-Day 2 – INK

Homework:  p.  471 #28-49, 56, 57, 64, 69; p.  473 #1-5

SEction 9.4 notes

An inscribed angle is an angle in the circle in which the vertex is a point on the circle and the sides of the angle are chords.  The measure of an inscribed angle is one-half the measure of its intercepted arc.

Homework:  p 470 #10-27

Decision Making:  You will have to decide whether to use the Law of Sines or the Law of Cosines to solve the triangle.   Check out the examples in this 8.6-ink. We also answered Questions 16 – 19 on page 434 in your book..  Homework:  p.  434, #20, 22, 26, 28, 30, 34, 37, 39, 43.   Ask me about # 26 in class tomorrow.

# Tuesday, April 2

We learned how to use the Law of Sines to solve a triangle.  To solve a triangle means to find the measure of each angle and to find the measure of each side.   Here is a video to watch on the Law of Sines.   Here is the link to see the Law of Sines – INK for today.  Homework:  p. 428  1-3, 4, 5, 6, 9   We also did STudy Guide 8.4 in class.

Students took a quiz today on SOH CAH TOA – on how to use the calculator.  Given the measures of the 3 sides of a right triangle, you should be able to write the sine, cosine, and tangent ratio of either one of the acute angles.    We also applied the skill that we worked on yesterday.   We worked on angles of elevation and angles of depreesion.  Here is a Angles of Elevation and Angles of Depression that students completed in class.  There is also another worksheet that is a review of SOH CAH TOA.
