Pupil outcome: I can use the formula for the cosine rule and the sine rule. Key learning points: - The cosine rule is useful when you know three sides and an angle are involved - The sine rule is useful when you know two pairs of sides...

Pupil outcome: I can consider which approach is useful considering the properties/restrictions of a problem. Key learning points: - At this point, you have multiple strategies available - By analysing the problem, you can determine which...

Pupil outcome: I can derive and use the formula for the sine rule. Key learning points: - The sides of a triangle are proportional to the sines of their opposite angles - A diagram can aid with understanding this - The sine rule is...

This video covers the basics of trigonometry. We cover the different equations you need to know to be able to fine missing sides, missing angles or areas of both non-right angle and right angle triangles.



This video is...

The area of a triangle is ½ the base X perpendicular height. If we don’t have the perpendicular height, there is another formula we can use: 1/2absinC which we look at in this video. We need two sides and the angle in between. This will...

In this video, the presenter explains how to use trigonometry to calculate missing angles and side lengths in non-right angle triangles. They describe two different methods, the sine rule and the cosine rule, and provide examples of when...

Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing...

The Sine This video is a lecture on the sine rule in trigonometry, focusing on how to use it to solve problems involving non-right-angled triangles. The video begins with an overview of trigonometry and the important ratios sine, cosine,...

The video is a lecture presentation on the sine rule, which is used to calculate missing side lengths and angles in non-right angle triangles. The presenter explains the three trigonometry ratios (sine Theta, Cos Theta, and tan Theta)...

👉 Learn how to solve for the length of the sides and the measures of the angles of a triangle using the law of sines. The law of sines is used in determining the length of the opposite side to a known angle measure or the measure of the...

In this lecture presentation, the focus is on the ambiguous case of the sine rule. The presenter uses two examples, one involving a triangle and the other a problem related to ships' bearings, to explain how to identify and solve the...

In this video we are going to discover what the sine rule is and how it works. For right angle triangles, we can use Pythagoras and SOHCAHTOA to find missing sides and missing angles. However, not every triangle is a right-angle...

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 1HR Q18, which involves finding the angle of a quadrilateral with an acute angle. By the end of the video, learners will understand the properties...
