This Demonstration constructs a triangle given the length of its base , the length of the altitude from to and the difference between the angles and at and . This is not one of Plemelj's original constructions, but a new one based on his equation , where and . It is the same as The Plemelj Construction of a Triangle: 8, but the verification is different.
