It is difficult to understand the code without labels in output using tkz-euclide.

To name label all points using single \tkzLabelPoints(all)

CODE from http://www.altermundus.fr/pages/euclide.html


    \tkzDefSquare(A,B)         \tkzGetPoints{C}{D}

    \tkzInterLC(D,C)(E,B)      \tkzGetPoints{T'}{T}

    \tkzDefMidPoint(D,T)     \tkzGetPoint{I}
    \tkzInterCC[with nodes](O,D,I)(E,D,I)   \tkzGetPoints{H'}{H}
    \tkzInterLC(O,H)(O,E)     \tkzGetPoints{M'}{M}
    \tkzInterCC(O,E)(E,M)     \tkzGetPoints{Q}{M}
    \tkzInterCC[with nodes](O,O,E)(Q,E,M)    \tkzGetPoints{P}{E}
    \tkzInterCC[with nodes](O,O,E)(P,E,M)    \tkzGetPoints{N}{Q} 

    \tkzDrawSegments[color=gray](O,H E,H E,F F',K)

enter image description here

Meaning of this (Unable to find in manual)

\tkzInterCC[with nodes](O,D,I)(E,D,I)   \tkzGetPoints{H'}{H}
  • Why not \tkzLabelPoints(A,B,....) ?

  • I think it would be better to ask a new question about the meaning of \tkzInterCC ... seeing as it's quite different from your original question (labeling nodes), and you already have an answer for that. Jul 30 '18 at 10:45
  • Any news here. Solved or still open?(if yes you could accept the given answer)

  • I made a choice : init, def, calc, mark and label. It’s difficult to find a process to get a good place to the label in all cases. Like AndréC wrote, I prefer to customize! Aug 13 '18 at 11:27
  • knowing all points will be useful to understand the new code, But for final picture placement of label can be decided.

The \tkzLabelPoints(all) option doesn't exist. You must enter all the names of the points \tkzLabelPoints(A,B,C,D,E,F,F',K,T,T',I,H,M,N,O,P,Q) or make a foreach.

But as you can see, aesthetically this option always places the label on below right which is not necessarily the most beautiful aesthetic effect.


It is more aesthetic to customize the placement of each point as for example with this code:

\tkzLabelPoints[above right](C,T,H)
\tkzLabelPoints[below left](A,O,M,P)
\tkzLabelPoints[above left](D)
\tkzLabelPoints[below right](B,Q,N)
