A regular tetrahedrom will have twelve angles of 60 degrees each. A tetrahedron is a figure with 4 faces, each face being an equilateral triangle. As a result there are 3 x 4 or 12 angles.
Each vertx has two adjacent angles.

"Tetrahedral" is an adjective. It needs a noun associated with it before it can be an abject that may have edges.
A square has four 90 degree angles at each corner
There are 6 angles in a tetrahedral structure.
The bonds between each C-H are slightly polar, I think. However, the molecule as a whole is nonpolar because of the molecule's tetrahedral position (the Hs surround the C symmetrically and with 90 degree angles between each H)
Octahedral structures are found in the study of molecular geometry. In an octahedral structure there are fifteen angles; twelve ninety degree angles and three one-hundred and eighty degree angles.
There are no angles in a linear structure. It is one line.
There are many compounds that exhibit tetrahedral structure. Some of those compounds are carbon tetrachloride (CCl4), chloroform (CHCl3), and methane (CH4). Many compounds of carbon (those which don't contain double bonds) are tetrahedral in structure because carbon tends to form four single bonds.
A trapezium has 4 right angles...Correction: it has 4 angles but they are not right angles. A structure/shape with 4 right angles is a rectangle or square.
The carbon is in the middle; this is a tetrahedral shape, and there are zero lone pairs.
Each vertx has two adjacent angles.
