Do you need to square a large project like a deck or flooring layout? The Greek math guru Pythagoras came up with a simple rule to make a 90 degree angle. Its the 3-4-5 triangle. This is applied to a project by measuring 3 feet on one leg, 4 feet on the next leg the measuring the two new points to make sure they are 5 feet (the hypotenuse of the triangle – see figure). ***This equation can be multiplied by any number for larger triangles. For example: x 5 = 15 ,20 ,25 and x 10 = 30 ,40 ,50.
