This self-checking worksheet contains three coordinate planes at the top of the page with either a sine, cosine or tangent value. Once the student solves each triangle, they are to work 9 problems using those triangles. (The triangles will not use radicals.) These 9 problems are 2 sine, 2 cosine, and 2 tangent problems, along with 1 cosecant, 1 secant and 1 cotangent. When the students are finished, they will discover a pun.
