This table's legs are the whole design: three identical truss-shaped assemblies, each built from two angled 4x4 pieces joined face to face with surface-mounted mending plates rather than any hidden joint. That's a deliberate industrial choice, not a shortcut — the plates read as hardware on purpose, the same way exposed bolts do on steel furniture.
Build one leg completely, then use it as a pattern to mark and cut the remaining two so all three actually match — with compound angles this steep (25° and 40° cuts), eyeballing each leg from the cut list alone invites small mismatches that show once all three are standing under a round top. If you don't have access to 4x4 stock, doubled-up 2x4s joined first with pocket holes and then the same mending plates works as a substitute.

Attach the two 4x4 pieces (main leg and leg foot) to a top 2x4 leg piece with 3" screws and glue, following your leg diagram for placement. Pound the mending plates into place across the joint on one side, flip the assembly, and repeat on the opposite face. Set this first leg aside as your pattern.
Using the first leg as your physical pattern, mark, cut, and assemble the remaining two legs the same way, checking each against the pattern before you commit glue. Matching legs matter more here than on a four-legged table — with only three legs, any one that's off is immediately visible.
If substituting doubled-up 2x4s for 4x4 stock, first join each pair with 1-1/2" pocket holes on the inside face, screw the six resulting leg sets together with 2-1/2" screws, then add the mending plates as above.
With the tabletop face down, position the three legs evenly spaced around the underside, then glue and screw each one down through the top leg piece.
