[MA2015] GEO (9-12) 27 : 27 ) (+) Construct a tangent line from a point outside a given circle to the circle. [G-C4]
[MA2015] PRE (9-12) 29 : 29 ) (+) Use special triangles to determine geometrically the values of sine, cosine, and tangent for π/3, π/4, and π/6, and use the unit circle to express the values of sine, cosine, and tangent for π - x,
π + x, and 2π - x in terms of their values for x, where x is any real number. [F-TF3]
