    Translated triangle perspective to a reference triangle - Clark Kimberling​

    Suppose A, B, C, D, E, F are points and L is a line other than the line at infinity. This work examines cases in which a translation D'E'F' of DEF in the direction of L is perspective to ABC, in the sense that the lines AD', BE', CF' concur.
