Q. The spherical surface of the geodesic dome comprises of
(A) Equilateral triangles of various sizes
(B) Isosceles triangles of various sizes
(C) Equilateral triangles of uniform size
(D) Isosceles triangles of uniform size
Ans: Equilateral triangles of uniform size
Explanation: Geodesic domes are based on Icosahedron whose triangular faces are then sub-divided into smaller triangles. An icosahedron has 20 faces, each of which is an equilateral triangle of uniform size.
