This is very simple to make, but people tend to be confounded by it because it's so different from modern pants.
Rotate the gusset 90" from how it's drawn, and connect the large angle with where the small angle was cut out (at the crotch). and the small angles at the ankles of the legs. Each side of the diamond goes down the legs.
If you use this pattern on DA, I'd like to see what you made.
