Where perpendicular bisectors meet; the center of the circumscribed circle.

When assembling multi-piece items, avoid tightening screws fully until all pieces are aligned to allow for minor adjustments. Notable Geometric Points

If you are building a physical piece, such as a triangle shelf or frame, use these common methods:

Where medians meet; the geometric center of the triangle.

Watch this brief explanation of why some rearranged triangular puzzles seem to have a missing piece due to slight slope differences:

To successfully form a triangle from three separate pieces, you must follow the . This rule states that the sum of the lengths of any two sides must be greater than the length of the third side. Valid Example: Sides of 3 ft, 4 ft, and 4 ft work because

Sides of 2 ft, 2 ft, and 7 ft cannot form a triangle because is less than 7. Woodworking Assembly
