Trigonometry

pastedGraphic_4.pngYou have a right triangle ABC with sides a and b and hypotenuse c. The length of side a is 6. The length of side b is 8. Find the length of side c and set up the 6 trig ratios (sin, cos, tan, csc, sec and cot) for angle A

Algebra: pastedGraphic_10.png

Geometry:  equilateral  all sides the same length all angles 60 degrees

                    isosceles  two sides the same length base angles congruent and measure (180 - vertex angle)/2

                    scalene  no sides the same length. smallest angle across from shortest side, largest angle across from longest side

Algebra II: x coordinate of the vertex is -b/2a  so -18/-6 or 3

                   plug into equation to find y coordinate of the vertex = 21

                   vertex (3, 21) opens down because a<0
