WebThis page shows how to construct a line parallel to a given line through a given point with compass and straightedge or ruler. This construction works by creating any triangle between the given point and the given line, then copying (translating) that triangle any distance along the given line.Since we know that a translation can map the one triangle … WebArmed with a straightedge, a compass and two points 0 and 1 marked on an otherwise blank “number-plane,” the game is to see which complex numbers you can construct, and which …
