There are certain quirks to putting blocks on point, but are well worth the effort.
You don't have to worry about that now. When you get all the blocks pieced and plain blocks cut (see above), you can find a ton of information about setting triangles - those are the pieces you need at the end of each row to make the quilt square again.
I colored them blue in the picture below so you can see them more clearly.
There are some basic important rules/guidelines as far as size and orientation but you they have no impact on making the blocks so you can wait on that. And there are a ton of tutorials and charts on the cutting measurements.
