The miter lap joint allows you to fit a stud into an assembled frame.

You can also, and more handily, start with a known dimension and find the other one. Say you know you want the legs to sit 3/4 inch deep into the top of the beam. With the straightedge crossing the square at the 7 and 24 as before, measure in to find the point where the straightedge is 3/4 inch from the edge of the square. The other leg of the right triangle thus formed is the distance to mark down the side of the beam—in this case, very close to 2 9/16 inches.

With all this Cartesian geometry, you'll be glad to get to sawing the diagonals and chiseling out the waste in the top beam notches. Since the legs splay out, you'll need to cut them about 25 1/2 inches long to have a 24-inch-high horse. The tops and bottoms of the legs must be cut with a compound bevel. If mathematical precision is your priority, you could figure all this out with advanced geometry, but that would be putting Descartes before the horse. Instead, just stick the leg stock into one of the notches in the top beam and saw it off flush with the top. Turn the piece end for end, set it in the opposing notch extended to the desired length, and saw it off flush with the top. This leaves you with one finished sawhorse leg and the start of the next one.

The dovetailed lap joint can also befitted into an assembled frame, but is strong in tension as well as in compression.
The dovetail tenon connects a stub joist to the plate.
