Pythagoras' Theorem Homework task __Fixing the flagpole__ A flag stands in the centre of a rectangular field that measures 5 m by 6.5 m. Stephen is trying to determine how to support the flagpole using guy wires. Stephen wants the flagpole to be supported by four guy wires that reach to the four corners of the field.
 * 1** Draw a diagram of the situation, then find the length of the diagonal of the field.
 * 2** Find the distance of the base of the flagpole from each corner of the field.
 * 3** Find the total length of guy wire needed if they are to connect at a point 8 m up the flagpole.
 * 4** Stephen realises that he only has enough material to construct guy wires of 30 m in length in total. How long will each guy wire be?
 * 5** Where on the flagpole will Stephen need to attach the guy wires, if they are still to reach to each corner of the field?
