Trig*Star is an annual competition that recognizes the best student of trigonometry from school districts across Texas. The goals of Trig*Star are:

• to promote excellence in the mastery of trigonometry in high school.
• to honor high school students who have demonstrated their superior skill among classmates at the local and statewide level.
• to acquaint high school students with the use and practical applications of trigonometry in the surveying profession.
• to build an awareness of surveying as a profession among mathematically skilled high school students, career guidance counselors, and high school math teachers.

Trig*Star is an extra-curricular activity held each year across the state of Texas. The competition is a timed exercise in solving trigonometry problems that incorporate the use of right triangle formulas and the laws of sines and cosines. Contestants have up to one hour to complete the regional test, and the person who achieves the highest score in the shortest amount of time wins.

Trig*Star is co-sponsored by the National Society of Professional Surveyors and the Texas Society of Professional Surveyors.
