1. A measurement and positioning arrangement for defining a 90 degree angle for positioning the corner of a building foundation, said arrangement comprising:
- a first stake being configured to be disposed in the ground;
a second stake being configured to be disposed in the ground a distance from said first stake;
a first string being configured to be tied between said first stake and said second stake;
a laser device;
said laser device comprising;
a hook structure being configured to hang said laser device from said first string;
at least one laser beam projector being configured to project a laser beam from said laser device substantially perpendicular to said first string; and
a bubble level being configured to permit a user to verify a level position of said laser device with respect to the ground;
a third stake being configured to be disposed in the ground a distance from said first stake and in the path of said laser beam projected from said laser device hanging from said first string;
a fourth stake being configured to be disposed in the ground a distance from said third stake and in the path of said laser beam projected from said laser device hanging from said first string; and
a second string being configured to be tied between said third stake and said fourth stake to intersect with said first string to define a 90 degree angle and a location where a corner of a building foundation will be placed.

2. A measurement and positioning device for defining a 90 degree angle for positioning the corner of a building foundation, said device comprising:
-
a hook structure being configured to hang said measurement and positioning device from a string tied between two stakes; and
at least one laser beam projector being configured to project a laser beam from said measurement and positioning device substantially perpendicular to a string from which said measurement and positioning device is suspended to define a 90 degree angle and a location where a corner of a building foundation will be placed.

3. A method of defining a 90 degree angle for positioning the corner of a building foundation, using a measurement and positioning device for defining a 90 degree angle for positioning the corner of a building foundation, said measurement and positioning device comprising:
- a hook structure being configured to hang said device from a string tied between two stakes; and
at least one laser beam projector being configured to project a laser beam from said measurement and positioning device substantially perpendicular to a string from which said measurement and positioning device is suspended to define a 90 degree angle and a location where a corner of a building foundation will be placed;
said method comprising the steps of;
placing a first stake and a second stake in the ground on a line where a side of a building foundation will be located;
tying a string between said first stake and said second stake;
hanging said measurement and positioning device from said string; and
switching on said measurement and positioning device to supply power to said at least one laser beam projector to project a laser beam from said measurement and positioning device substantially perpendicular to said string to define a 90 degree angle and a location where a corner of a building foundation will be placed.
- a hook structure being configured to hang said device from a string tied between two stakes; and
