Web4 Jan 2024 · Recall that when making Half square triangles, you will add 7/8" to your finished size, then cut on the diagonal. To make Split Rectangles, first determine the finished size of your rectangle, then add ½” to the width and height. You can add a little more if you want to give yourself a little more wiggle room. In linear algebra terms, the use of a block matrix corresponds to having a linear mapping thought of in terms of corresponding 'bunches' of basis vectors. That again matches the idea of having distinguished direct sum decompositions of the domain and range. It is always particularly significant if a block is the zero matrix; that carries the information that a summand maps into a sub-sum.
