planimetry|pləˈnɪmɪtrɪ|
Also 4 planemetrie; 7 planametrie, -ye; 8–9 plano-.
[Ultimately f. L. plān-us flat + -metria, -metry, on L. type plānimetria; the ME. planemetrie prob. represents an OF. form; but F. planimetrie appears only as of 1520 in Godef. Compl., and med.L. planimetria is cited only from 16th c., though prob. used much earlier. Planametry and planometry are formed on less correct analogies.]
The measurement of plane surfaces; the geometry of plane surfaces, plane geometry.
