This set of 20 trigonometry worksheets, created to follow up the popular "PUZZLE MATH: Trigonometry and Logarithms", provides instant feedback and fun to students because the answers correspond to letters/images that decode secret messages/pictures. They are self-checking, ideal for customized treatment of learners. Students identify reference angles and quadrants, evaluate trig functions using special right triangles, find trig functions’ values when given terminal side points, use/prove trig ids, evaluate trig funcs. using calculators, find sinusoid attributes like amplitude, evaluate inverse trig functions, solve equations with trig functions using factoring and Pythagorean Identities for multiple values, and use the Laws of Cosines and Sines and triangle areas. They also find sides/angles using trig definitions, complete the Double & 1/2 Angle Identities, Use Sums and Differences of Angles & 1/2 Angle Identities, differentiate which techniques to use on mixed reviews, and more.
