#### Triangle Solver

This simple calculator will work out the lengths of the sides and the size of the angles of any triangle given thee particular pieces of information.

This game is intended to provide a little bit of fun with a loose mathematical connection. There is of course mathematics involved in knowing the angle and stretch required to get the cat to the correct shelf. There is also mathematics involved in following the instructions about the number sequences.

The sequences appear here for those who have a Transum Subscription.
