#### Pythagoras or Trigonometry ???

A flow diagram that will help pupils decide if they should use Pythagoras or Trigonometry.

A flow diagram that will help pupils decide if they should use Pythagoras or Trigonometry.

This worksheet separates out the trig questions, and first asks pupils to fill in theta, opposite, adjacent and hypoteneuse, then write out with trigonometric ratio they are using.
Scaffolding to solve problems.

TES PICKS

Two trigonometry codebreakers that both involve a terrible joke. The first one is with right-angled triangles, the second requires the sine rule, cosine rule and area of a triangle using trigonometry.

TES PICKS

An end-of-unit quiz on trigonometry (with some pythagoras and other geometry thrown in) for GCSE classes.
I originally made this as a presentation on Google Docs. A link to the original and the .pdf version are both shared below.

Algebra 2/Trigonometry: 20 page Polar and Rectangular Coordinates includes brief notes, examples, and practice test (with detailed solutions).. Topics cover converting polar to rectangular; plotting polar coordinates; complex number system, and more; Also, imaginary numbers quiz, and 3 comics. Available at mathplane.org. (Or, download here and support mathplane and TES.). Thanks for visiting!

Challenge your students to become the surveyors of a new national park in this trigonometry project. Students apply the law of sines, law of cosines, and more to complete the survey. Two options for finishing the project: one includes finding the area of non-right triangles and the other does not require students have learned the concept yet. An engaging addition to your Pre-Calculus curriculum. Student-tested and approved!

This is a set of 16 trigonometry task cards requiring students to use knowledge of basic trig functions to find unknown sides and angles. Students will be required to use all the trig functions and some inverses to find unknown values. We've also incorporated a little cross curricular fun by adding some of the most famous and tallest buildings into the word problems. These are sure to be a hit!

Trigonometry Relay Race

We've made a trigonometry version of our beloved relay race! In the trigonometry relay race, students are required to use knowledge of:
- sine, cosine, tangent
- inverse to determine angles
- converting degrees to radians and radians to degrees
- the unit circle
- finding unknown sides using trig functions
- exact values of common angles
- relationships between sine, cosine and tangent
Now with an answer key and equation bank!
Our students always love the relay race and is our favorite review for students.
