There is disclosed a template for providing multi-sided figures such as figures having 5, 6, or more sides. Essentially, the template is a planar member having a bottom apex. Directed from the apex, at a given angle, with respect to the horizontal, are two sides each of opposite slope. The member has a central vertical axis which is directed from the bottom apex and along which are a series of indicators spaced according to a desired length of a side. Positioned on the planar member are two slots which are parallel to the sloping sides emanating from the apex. Each indicator along the vertical axis is manifested by lines which are drawn from the indicator to the corresponding slot. In order to construct a polygon, the user emplaces a tack or pin through an indicator of the central axis to determine the length of the side and then marks the surface upon which the polygon is to be drawn by imprinting a mark where the connecting indicator line intersects the slot. A first corner is then scribed by marking two lines on either side of the apex. The unit is then rotated in position until a mark corresponds with a line on the opposing side. In this manner all corners of the figure are denoted in turn to provide the polygon of a given number of sides as determined by the apex angle.
