## The Wonder and Amusement of Triangles - Part Five : the Law of Tangents

Moving on then from Sine and Cosine Rules, we now look at a less well now known principle, and this involves what is known as the Law of Tangents.

### They Came

This story I wrote 20 years ago for a competition. It won no prize and is unpublished. To my knowledge, it is all my own work. Although it deals with visitors from space, I have no belief in them.

### Bartholomew Webb

I first wrote this 20 years ago for a writing course I paid a fortune for but never finished. I read it publicly once, and though submitted elsewhere it hasn't til now been published. All mine.
