Quandaries
and Queries 

Dear Expert, My name is Tiffany I am a student and the level is a secondary question. 

Hi Tiffany, We have received this question many times. One example, given by Claude, is familiar to many people who have built a fence. The following six examples come for people who have asked us to help with a problem. These are not "made up" school problems but real problems that have arisen in their work or home lives.
Each of these involves a use of Pythagoras' Theorem in the solution. The last, which is my favourite, does not mention Pythagoras' Theorem explicitly, but the expression used to find the length of HB is Pythagoras' Theorem. Penny
