Problem

Given a point C, a point Hc and a point Ta, construct the triangle ABC.

Status

ArgoTriCS says that the problem is solvable.

Solution


  1. Using the point C and the point Hc, construct a line hc (rule W02);

    % DET: points C and Hc are not the same

  2. Using the point C and the point Ta, construct a line a (rule W02);

    % DET: points C and Ta are not the same

  3. Using the point Hc and the line hc, construct a line c (rule W10a);

  4. Using the line c and the line a, construct a point B (rule W03);

    % NDG: lines c and a are not parallel

    % DET: lines c and a are not the same

  5. Using the point B, the point C, the point Ta and the line a, construct a point T`a (rule W19);

    % NDG: points B and C are not the same points C and Ta are not the same points C and midpoint([B,Ta]) are not the same

  6. Using the point Ta and the point T`a, construct a circle k_over(Ta,T`a) (rule W09);

    % NDG: points Ta and T`a are not the same

  7. Using the circle k_over(Ta,T`a) and the line c, construct a point Awb and a point A (rule W04);

    % NDG: line c and circle k_over(Ta,T`a) intersect
