Transversals of a triangle and the Euler line

1. Create a triangle.
2. Create line bisectors of the sides.
3. Switch off drag mode to enable more exact positioning
4. Construct the altitudes of the triangle and intersect two of them
5. Construct lines connecting the corners with the midpoints of the sides. Their intersection is the centroid.
6. Construct the bisector perpendiculars. Their intersection is the circumcenter center.
7. Connect the three intersection points y a line. This line is called Euler line.
