As part of constructing a scalene triangle, Jordan drew a line segment and plotted one vertex of the triangle on the line segment. With this vertex as the center, Jordan drew an arc to create a 180 degree angle. How can Jordan ensure that the other two points he plots will represent the remaining two vertices of a scalene triangle?

Plot both the points on the line segment.

Plot one point on the arc and the other point beyond the arc.

Plot both points on the arc, one on the left and the other on the right.

Plot both the points beyond the arc.
