What is the significance of the 3-4-5 triangle in masonry?

The significance of the 3-4-5 triangle in masonry primarily lies in its ability to ensure right angles in constructions. This geometric principle involves forming a triangle where the lengths of the sides are in the ratio of 3:4:5. When a right triangle is constructed with these dimensions, it guarantees that the angle opposite the longest side (the hypotenuse) is a right angle, or 90 degrees.

In practical terms, when laying out a building foundation or aligning walls, the 3-4-5 method provides a reliable means of achieving square corners. By measuring three units along one side, four units along the other, and verifying that the hypotenuse measures five units, masons can create accurate right angles that are crucial for the structural integrity and aesthetics of the construction.

While the other options relate to important aspects of masonry, they do not directly pertain to the specific application of the 3-4-5 triangle. Understanding and applying this method is fundamental to successful layout and alignment in bricklaying and masonry work.
