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.

A square has four 90 degree angles at each corner

a pentagon has 5 angles. In a regular pentagon, there are no right angles. Each angle is 72 degrees. In a irregular pentagon, there may be right angles...not sure how many..depends on how you draw it
There are 6 angles in a tetrahedral structure.
Methane (CH4) is a common example of a molecule with tetrahedral geometry. In methane, the central carbon atom is bonded to four hydrogen atoms, arranged symmetrically in a tetrahedral shape with bond angles of 109.5 degrees.
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.
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)
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.
There are two possible structures for a tetrahedral molecule with the formula AHXYZ. One structure is where the central atom (A) is in the center of the tetrahedron, and the other is where A occupies one of the vertices of the tetrahedron.
Each vertx has two adjacent angles.
