Transum Trigomometry

SohCahToa

Transum Trigonometry is a collection of online exercises. The questions are presented one at a time in increasing order of difficulty. Levels 1 and 2 are self checking and you must get the current question right before going on to the next. When you have answered 5 correctly you are given the option of claiming a trophy or printing a certificate to show your achievement. The trophy and certificate will show how many questions you have answered correctly so you might want to wait before you print until you have answered as many questions as possible.

It is recommended that you write out all of your working in your exercise book and then check your final answser online.

Answers should be given to three significant figures.
