What are the geometrical construction methods used for straight and radius bends curved or circumference sections pyramid and cone sections?

For straight bends, a common method is to use a ruler and draw a straight line connecting the desired points. For radius bends or curved sections, a compass can be used to draw arcs of the desired radius. For pyramid and cone sections, methods such as triangulation or development can be employed to create the necessary shapes by unfolding them onto a flat surface. These techniques are essential in fields such as engineering, architecture, and design for accurately fabricating geometric shapes.
