In the plane of a triangle ABC, let DEF be a triangle and U a point. Except for special cases, there are at most two nontrivial U-dilations of DEF that are perspective to ABC. Of particular interest are configurations in which DEF is perspective to ABC, as when DEF is a cevian or anticevian triangle. Midcevian and mid-isotomic triangles are introduced. Many loci associated with perspectivities among these triangles are Z cubics.
