A triangle is split into two parts by drawing a line from one side to the base of the triangle. The ratio in which the sides are split is shown for each of the sides connected by the line. The task is to find what multiple of the smaller triangle is the larger triangle.

The ‘something in common’ between each...

A circle is drawn that is tangent to the three sides of the triangle. The two constituent lengths of the hypotenuse are given and the challenge is to calculate the area of the triangle. When...

This activity is based upon a practical task to fit a set of similar triangles into a spiral. It is in two parts, the first of which is more accessible.

In Part 1 students are presented with a series of different sized similar triangles. These fit together to form a spiral and students look at how many are...

This task considers using metal rods to make a triangular framework. The metal rods have lengths that are whole numbers. Students must work out how many triangular frameworks can be made with the longest side being 7 metres. The solution involves being methodical in listing examples, and using inequalities to...

This resource contains two interactive excel files dealing with the graphs of trigonometric functions.

Trigonometry: X=cos, Y=sin...

Royal Navy Search and Rescue helicopters provide cover to large sections of the UK coastline, offering support to coastguard services 365 days a year.

These materials from Defence Dynamics encourage the use of problem solving skills and knowledge of trigonometry to directly assist the Royal Navy in a series...

The objectives of this PowerPoint are for students to:

• understand what is meant by: circular functions; quadrants; positive angles; negative angles.
• recall the main characteristics of the graphs of y = sin x, y = cos x and y = tan x.
• consider the main trigonometric ratios in all 4...

Mathcentre provide these resources which cover aspects of trigonometry, often used in the field of engineering. They include the trigonometric ratios, using Pythagoras’ theorem and working with the sine and cosine rules.

Comprehensive notes, with clear descriptions, for each resource are provided, together...

This resource is designed as a resource bank of questions to supplement the teaching element of the lesson. The questions require students to use Pythagoras' theorem in order to find whether a triangle is right angled and find the lengths of missing sides, and problems on 2D and 3D shapes.

The next section...

This resource consists of 15 instant maths ideas, ideal for use as starter questions, extension question or probing questions to assess understanding, requiring students to plot graphs of the trigonometric functions and explain their properties, explore Snell’s Law, convert gradients into angles, calculate the...

This MEP resource from CIMT is taken from text book 9B which covers the mathematics scheme of work for the second half of year 9.

Trigonometry covers: Pythagoras' theorem, trigonometric functions; an introduction to sine, cosine and tangent; calculating the length of sides of triangles and calculating the...

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of trigonometry, from an investigation leading to Pythagoras’ theorem to using the sine and cosine rules.

Trigonometry pack one contains nine work cards...

This poster illustrates how expertise from designers, engineers and technologists is used to design and manufacture an innovative snowboard. It helps to illustrate how STEM industries offer many exciting career opportunities.

Students are required to draw graphs to represent data and critique an incorrect interpretation of the data. Given the results of a survey, students draw a chart or graph of the discrete data provided to help explain why the interpretation of the results provided is incorrect and are required to draw their own...
