Test Review!

Learning Goals from the Unit I can solve proportions I can determine angle relationships involving triangles and parallel lines (all inside angles = 180, Z pattern, F pattern, X pattern, etc) I can find side lengths of similar triangles I can find triangle side lengths using sine, cosine, and tangent I can find triangle angles using sine, cosine, and tangent (taking the inverse!) I can solve problems involving similar triangles, Pythagorean Theorem, and Sine, Cosine & Tangent (“Primary trig. ratios”)

Important Terms ALWAYS angles made with the HORIZON!!!!

What do we do with this one? You can’t solve this one! You either  Forgot to put in some information  Chose the wrong ratio (Can you do sine or cosine with the other sides?)  Need to find some other information first (Use all the angles add to 180, Pythagorean Theorem, or another ratio)

How do you decide which method to use? Pythagorean Theorem a 2 + b 2 = c 2 Sin A = opp/hypCos A = adj/hypTan A = opp/adj - When you have 2 sides of a right triangle and need the 3 rd side You have 2 of: -Angle -Its Opp Side -The Hyp And you need the one leftover You have 2 of: -Angle -Its Adj Side -The Hyp And you need the one leftover You have 2 of: -Angle -Its Opp Side -Its Adj side And you need the one leftover Use …

Which do we use? θ

Work Time! Not talk time!
