Guidelines for Drawing a Graveyard Plan

Drawing a Graveyard Plan

Some Useful Geometry

Two ways to plot a right angle:

Choose distances x and y to avoid
obstacles.
Greater distances will produce a more
accurate result.
second diagram of how to plot a right angle

This method is useful when there are
obstructions on one side of the line.
Any multiples of 3, 4 and 5 can be used,
for example, 6, 8 and 10 metres.
You could also use multiples of 5, 12 and 13.

Checking that the grid is 'square':

A true rectangle has equal diagonals A and B.

A is shorter than B because the grid is 'off square'.
