I am trying to construct a triangle with 2 altitudes. It worked for ‘All’ vertices.
a = {5, 0}; b = {0, 0}; c = {3, 6}; tri = {a, b, c}; alt = TriangleConstruct[tri, {"Altitude", All}]; Graphics[{Style[Triangle[tri], Opacity[0.2]], alt}] But when I tried to specify two vertices,
alt = TriangleConstruct[tri, {"Altitude", {a, b}}]
The following message came out:
TriangleConstruct is not a Graphics primitive or directive.
How do I specify two vertices to draw the altitudes?
