Triangle[{p1, p2, p3}] represents a filled triangle with corner points p1, p2, and p3. Triangle[{{p11, p12, p13}, ...}] represents a collection of triangles.

A standard triangle in 2D: In[1]:=Graphics[Triangle[]] Out[1]= A triangle in 3D: In[1]:=Graphics3D[Triangle[{{0, 0, 0}, {1, 0, 0}, {0, 1, 1}}]] Out[1]= Different styles applied to Triangle: In[1]:=ℛ=Triangle[{{0, 0}, {1, 1}, {2, 0}}]; {Graphics[{Pink, ℛ}], Graphics[{EdgeForm[Thick], Pink, ℛ}], Graphics[{EdgeForm[Dashed], Pink, ℛ}], Graphics[{EdgeForm[Directive[Thick, Dashed, Blue]], Pink, ℛ}]} Out[1]={, , , }

Triangle[{p_1, p_2, p_3}] represents the filled triangle with vertices p_1, p_2 and p_3, where each p_i is specified as a list with length corresponding to the embedding dimension. Most commonly, the vertices of a Triangle are lists of length two (giving a triangle in the 2D plane) or three (giving a triangle embedded in 3D space). The zero-argument form Triangle[] evaluates to the standard 2-simplex Triangle[{{0, 0}, {1, 0}, {0, 1}}]. The syntax Triangle[{{p_11, p_12, p_13}, ..., {p_(k1), p_(k2), p_(k3)}}] may be used to represent a multi-triangle collection.
