Trigonometry Revision SINE COSINE and TANGENT Ratio Right Angle Triangle Revision. In detail step by step answers. Very Visual and engaging.
Great for whole lesson or quick fire revision.
Working out missing length / side/ angle for a right angle triangle.
Excellent Demonstration Videos', there is one for 3D Trigonometry as well.
Comprehensive explanations on SIN / COS/ TAN Ratios being used for side / length and Angle.
Comes with solutions / answers.
Has 'spot the wrong answer' questions to draw out deeper understanding.
Trigonometry SOH CAH TOA.
A complete lesson on using SOHCAHTOA and Pythagoras’ theorem with problems in three dimensions.
Activities included:
Starter:
A set of recap questions on basic SOHCAHTOA and Pythagoras.
Main:
Examples and questions to dscuss, on visualising distances and angles within cuboids and triangular prisms, and understanding the wording of exam questions on this topic.
Examples and quick questions for pupils to try, on finding the angle of a space diagonal.
A worksheet, in three sections (I print this, including the starter, two per page, two sided so that you have a single page handout), with a progression in difficulty. Starts with finding the space diagonal of a cuboid, where the triangle pupils will need to use has been drawn already. The second section looks at angles in a triangular prism, and pupils will need to draw the relevant triangles themselves. The third section has exam-style questions, where pupils will need to identify the correct angle by interpreting the wording of the question. (eg “find the angle between the diagonal AE and the plane ABCD”).
An extension task looking at the great pyramid of Giza.
Plenary:
A final question to add a bit more depth, looking at the most steep and least steep angles up a ramp.
Printable worksheets and worked answers included.

Single Worksheet and Answer Key/Mark Scheme on Angles of Elevation and Depression
The activity is based off of the IGCSE 0580 standard which states:
E6.2 – Apply Pythagoras’ theorem and the sine, cosine and tangent ratios for acute angles to the calculation of a side or of an angle of a right-angled triangle.
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.

This is the first lesson introducing the topic of Trigonometry. This lesson is about building an understanding of what trig is by doing various rich tasks and activities and starting to use SOHCAHTOA. This lesson is ready to go, with no prep required. It is also great for home learing. 23 slide presentation + extra resources.
The lesson comes with:
+ a Starter
+ Learning Objectives (differentiated)
+ keywords
+ superb teaching slides (offering a very detailed explanation)
+ lots of examples to follow
+ Embedded Activities
+ Questions (with answers)
+ Handout (to support student notes)
+ Worksheet (with answers)

A resource that took me 5 lessons to go through. So there’s a unit here.
(Adding in a few little worksheets I found online for some extra questions)
Introduces sin and cos separately, using similar triangles.
Then moves onto trig tables, so students aren’t just pressing a ‘magic’ button on their calculator.
Then a little exercise choosing between them.
Then tan.
Then choosing sin/cos/tan.
Then angles.
Lots here. Lots of questions, lots of examples.
No challenging or problem solving questions. This was meant as an introduction.
IGCSE Trigonometry powerpoint slides and worksheets. Exercises indicated are with reference to IGCSE Cambridge Maths Student’s book ‘Collins’.
Very easy to understand slides.
Power-point of Trigonometry and exact values. It got Trig ratios formula’s. This is only Year 10 & 11. Also got nine examples for you. You may print off any slides. You can use this as a revision for the students test. Slide 21, you can create 6 questions of your own but the slide has cut in half.
This is an excellent whole lesson on Bearings and Trigonometry with resources to teach a subject that is often done poorly in exams. The lesson involves using understanding bearings but also how often it is incorporated with trigonometry and therefore a good existing level of trigonometry is required. This lesson is ready to go, with no prep required. It is also great for home learning. 16 slide presentation + resources.
The lesson includes:
Starter (linked to angle rules)
Learning objectives (differentiated)
Keywords, Rules and Notation
Lots of great Examples
