7.They are naked viruses, about 30 nanometers in diameter, and they're surrounded by an icosahedral capsid, which is a spherical protein shell made up of 20 equilateral triangular faces.
8.Human herpesvirus 8 is a large double stranded linear DNA virus surrounded by an icosahedral capsid, which is a spherical protein shell made up of 20 equilateral triangular faces.
9.In the first course, there was a shoulder of mutton cut into an equilateral triangle, a piece of beef into a rhomboides, and a pudding into a cycloid.
10.The old man's route being along one side of an equilateral triangle, while Jim's was along two sides of the same, the former was at the point of intersection long before Hayward.
11.So this leaves us, somewhat disturbingly, with three different possibilities: All triangles really are equilateral, that's just the truth of the universe, or you can use Euclid-style reasoning to derive false results, or there's something wrong in the proof.
