👉 An orthoceratoid is a type of shape, which can be defined as having three vertices that are all located on the same straight line. Specifically, an orthoceratoid has vertices that are at right angles to each other (orthocenter) and also have three edges that are perpendicular to each other (hypotenuse). In other words, it is a shape with three straight sides that are perpendicular to each other and all of its vertices lie on the same line.
