Review / In Class

In triangle JFK J j

JF = 5.00”

JK = 13.0”

<f = 90º F f k K

Find:

FK = _________________ ”

<j = _________________

<k = _________________

Lesson TWO 3/30/12

-- Margaret Thatcher

“"The trouble with socialism is that eventually you run out of other people’s money…"

Do Now:

Find the missing sides and missing angles:

<A = 17 a = 2

<B =__ b = ___

<C =___ c = 4

test

Sin(17) / 2 = Sin(C) / 4

0.1462 *4 = Sin(C) 

<C = ArcSin(0.5847) = 35.7849

180 – 17 – 35.7849 = <B = 127.2151

127.2151

5.4477

35.7849

Your not going to like this!

<C also could = 144.2151

<B also could = 18.7849

Side b also could = 2.2028

Properties of Parallelograms:

Page 330

-Opposite Sides Congruent

-Opposite Angles Congruent

-Consecutive Angles = 180 (supp)

-Diagonals Bisect each other
