Use GeoGebra tools to find the position of the main special points of the triangle, then verify your construction by selecting the related check box.
Drag the vertices of the triangle, and explore how the special points position changes, depending on the characteristics of the triangle (acute-angled, obtuse, right triangle ....)
Check the Euler line box to explore the alignment property of orthocenter, barycenter and circumcenter.
Use the measuring tools of GeoGebra to verify the property
