Abstract
We had measured hypophseal triangles in cranium f aciale of Macacus f uscatus (Blyth) before And this time we have examined cranium cerebrate triangles of it.
In the fronto triangle of Macacus fuscatus (Blyth), the ∠ PNBr of Δ PNBr is smaller than the human race at comparative anatomy.
In the parietal triangle of the Δ PBrL, particularly, ∠ PBrL is larger than the human being.
The quadrilateral PNBrL of Macacus fuscatus (Blyth) is about a parallelogrom, and the Δ NBrL of human forms about an isosceles triangle that ∠ NBrL is a vertex.
The three angles of human's Δ PLB is forming a high isosceles triangle that PB side is bose, but the angles of Macacus fuscacus (Blyth) is forming a rightangled triangle that PB side is base.
