Web11 apr. 2024 · In geometry, a median is a line segment from an angle of a triangle to the midpoint of the opposite side of a triangle. A median may or may not be perpendicular to the side of the triangle. The intersection of the 3 medians is called a centroid. In the case of some triangles like the equilateral triangle, the median, and altitude are the same. WebAnswer (1 of 7): Let the triangle be ∆ABC with vertices A,B and C with length of each side L. Each angle will be 60° L=AB=BC=CA Draw 3 angle bisectors(or 3 altitudes or 3 medians). These all meet at a single point which is the center of the equilateral triangle. Let the centre be D.
