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 sides or missing angles in any triangle (right angle or not). We label the sides as a, b and c, and angles as A, B and C. We need to work out whether to use the sine rule or the cosine rule. The sine rule is easier, so look for that one first. The sine rule is based on opposite pairs: you need an angle and the side opposite it, then you need either an angle and you want the opposite side OR you need a side and you want the opposite angle. If we don't have the right combination of sides and angles for the sine rule, then we can use the cosine rule. For the cosine rule, we either want all three sides and to be looking for an angle, OR we need to have a side, angle and side all next to each other, and to then be wanting to find the third side.

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 triangle. For non-right angle triangles we have the sine rule and the cosine rule. The sine rule can be used to find either missing sides or missing angles in any triangle (right angle or not). The sine rule is based on opposite pairs - an angle and the opposite side. We therefore label sides as a, b and c, and angles as A, B and C. We can then simply substitute in the values to find the missing side or the missing angle. If we're looking for a missing side, we use the formula (a / sinA) = (b / sinB). Whereas to find a missing angle we use (sinA / a) = (sinB / b).

Sine Rule Example ( GCSE / IGCSE )

This video shows you how to use the sine rule to find unknown angles in a triangle. This is part of the extended (or higher level) curriculum for GCSE / IGCSE. #GCSEmaths2022 #IGCSEmaths2022 Transcript: This video is going to use the following exam question to teach you about the sine rule, which is sometimes called the law of sines. So in this question we’re asked to use the sign rule to find the angle ACB, which is the angle here. Now, the sine rule can be used on any triangle (i.e. not just right-angled triangles, like some of the triangle laws) providing you know one of the angles and the length of the side opposite that angle. And when this is true we can find the size of an unknown angle providing that we know the length of the side that is opposite. When this is true we can use the sine rule, which is as follows. So the sine rule states that the length “a” divided by the sine of angle “A” is equal to the length “b” divided by the sine of angle “B”, which is equal to the length “c” divided by the sine of angle “C” Note that the length is always opposite the angle, so length “a” is here because it is opposite angle “A”, and length “b” is here because it is opposite angle “B”, and so on … One thing to note is that you never need to use all of the sine rule. For example, in this question we do not know angle “A” and length “a” so we can ignore this part of the sine rule and just deal with the parts containing “b” and “c”. So when we get to this stage we simply input the information that we know from the diagram. So we know length “b” and length “c”, as well as angle “B” and we want to use this equation to find angle “C”. Now this requires some rearrangement to get to the final answer because the angle we want to find is in the denominator (i.e. on the bottom of the fraction) and we need it to be in the numerator at the top. Now we can make this change using the algebra rules you will find in my other videos so if you don’t understand the steps that I show you next it might be a good idea to check out my other videos. However, here we’re in a situation where we can cross-multiply, so these two values can be swapped to give the following, which results in the unknown angle “C” moving to the top, as required. To get angle “C” on its own we multiply both sides by the sine of 84.3 degrees, which has the result of moving this sine value here leaving the sine of the angle “C” on its own. We are now very close to finding the size of angle “C”. If you use a calculator to work out the right-hand side, you will find that the sine of C is equal to 0.327 something And if we take the inverse sine of this value we can find angle C, and your calculator should show you that this is 19.142 something … If we round this to three significant figures we can conclude that the size of angle C rounds to 19.1 degrees. So we have therefore used the sine rule to find the size of an unknown angle. It is my hope that this helped. Subscribe if you’d like more and press like and share if you’d like the video to reach other students. All the best.
