.

**The Cosine Rule **can be used on any triangle for finding lengths and angles. Consider the triangle below.

.

For triangles with two lengths and an angle in-between, the third length can be found using the cosine formula for finding length.

. a² = b² + c² – 2bccosA

For triangles with three lengths, any of the three angles can be found using the cosine formula for finding angles.

.

You need to know how to label the sides of the triangle and what to substitute into the formula.

Thanks to the SQA for making these available. Questions & answers have been split up by topic for your ease of reference.
