This is a set of 4 mastery worksheets on trigonometry involving the Sine rule, Cosine rule, area of triangles using trigonometry and exact trig values.
Each worksheet is split into 3 sections, fluency, reasoning and problem solving so students can master the topic.
All answers are included for the questions.

A complete lesson on using sin, cos and tan to find an unknown side of a right-angled triangle. Designed to come after pupils have been introduced to the trig ratios, and used them to find angles in right-angled triangles. Please see my other resources for complete lessons on these topics.
Activities included:
Starter:
A quick reminder and some questions about using formulae triangles (e.g. the speed, distance, time triangle). This is to help pupils to transfer the same idea to the SOHCAHTOA formulae triangles.
Main:
A few examples and questions for pupils to try, on finding a side given one side and an angle. Initially, this is done without reference to SOHCAHTOA or formulae triangles, so that pupils need to think about whether to multiply or divide.
More examples, but this time using formulae triangles.
A worksheet with a progression in difficulty, building up to some challenging questions on finding perimeters of right-angled triangles, given one side and an angle.
A tough extension, where pupils try to find lengths for the sides of a triangle with a given angle, so that it is has a perimeter of 20cm.
Plenary:
A prompt to get pupils thinking about how they are going to remember the rules and methods for this topic.
Printable worksheets and answers included.

A set of questions in real-life scenarios, where pupils use SOHCAHTOA to find angles an distances.
Activities included:
Starter:
Some basic SOHCAHTOA questions to test whether pupils can use the rules.
Main:
A set of eight questions in context. Includes a mix of angle of elevation and angle of depression questions, in a range of contexts.
Printable worksheets and answers included.

A complete lesson on using and applying Trigonometry to right angled triangles which is suitable for the new curriculum.
Pupils are given the chance to master the fluency of this topic aswell as work on reasoning and problem solving tasks.
All tasks are differentiated to 3 levels all with solutions and offer lots of consolidation as well as alot of challenge. Can be used with KS3/KS4.

A complete revision lesson for pupils to practice SOHCAHTOA, both finding sides and angles.
Activities included:
Starter:
A set of questions to test whether pupils can find sides and angles, and give a chance to clear up any misconceptions.
Main:
A treasure hunt of SOHCAHTOA questions. Straight forward questions, but should still generate enthusiasm. Could also be used as a a more scaffolded task, with pupils sorting the questions into sin, cos or tan questions before starting. Activity has been condensed to two pages, so less printing than your average treasure hunt!
Bonus:
Another set of straight-forward questions, that could be given for homework or at a later date to provide extra practice.
Printable worksheets and answers included.

This is a Pret homework for trigonometry in right-angled triangles. In Pret homeworks, pupils practise, recall, extend and think. These homeworks are typically followed in class with spelling or memory tests and discussions about research findings. For an editable version of this homework and Pret homeworks for many more topics, see http://prethomework.weebly.com/.

PowerPoint presentation to introduce the topic of trigonometry, either at KS3 or GCSE level maths. Includes background behind why we use trigonometry, some examples with answers, with a question for students to complete at the end. Includes a recap of everything learned.
Brilliant for students with no previous understanding of trigonometry, or those looking to revise/re-learn the basics.

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.

A set of matching activities to help students practise finding the missing sides and angles in triangles using SOH CAH TOA.
This pack includes four activities:
1. Label the Sides Worksheet
A quick activity for students to label the sides as opposite, adjacent or hypotenuse to get them ready for using SOH CAH TOA.
2. Matching Activity 1 (Sin & Cos)
Students must use the sine and cosine ratios to find the missing sides in a set of triangles.
3. Matching Activity 2 (Sin, Cos & Tan)
Students must use sine, cosine and tangent ratios to find the missing sides.
4. Matching Activity 3 (Angles)
Students must calculate the missing angles in a set of triangles and match them to their answers.
All activities include answers and are easy to check as students can record their answers in a table, meaning you can quickly assess if they are on the right track.

This PPT is ideal for introducing trigonometry to higher tier GCSE Mathematics students. It covers:
Basic trigonometry using SOHCAHTOA
3D Trigonometry
Advanced Trigonometry
A poster which can be used by students to understand when to use different trigonometric methods

Notes, examples, questions and answers illustrating the use of trigonometry in solving problems. Diagrams are given for many of the questions but some problems are included which require the construction of a sketch diagram. This unit of work is suitable for self-study and ranges from beginner to GCSE level.
Three exercises containing a total of over 60 questions (with separate answers) are included in this resource of 20 A4 pages.

This is the original resource for the following topics
Introduction to Trigonometry
Solving basic equations
Rules for Trigonometry
Trigonometric graphs using radians
Solving Trigonometric equations involving radians
This resource includes:
Full PowerPoint in powerpoint format with all the slides
