An expandable tool for laying out and marking predetermined angular layout lines on a work surface. The tool is comprised of a first leg (202), second leg (204), and hypotenuse leg (206) which are assembled by the user such that the intersection of the first and second leg form the desired angle as defined by the hypotenuse (206). The general shape of the assembled tool will normally be a triangle. Each leg of the tool can consist of a single leg portion (or member), or alternatively, each leg can be made up of more than one leg portion. The ends of each leg are fitted with a fastening mechanism (214) for connecting the leg portions together. The tool can be made to various sizes by the addition and deletion of leg portions. Additionally, the tool can be disassembled to facilitate compact transport to subsequent work sites.
