If the corners of the seat are at right angles (square), then the angle cuts required on the decking boards, at that corner, will be 45degrees, but if the corners of the seat are anything other than right angles, then that angle will be the line from A to B as shown in the seat frame drawing in the previous page.
Next lay and To secure with nails or screws. the 3 intermediate decking boards in the same way as the two outside boards ensuring the gaps between them are even.
