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 Lewis dot structure of CH4 contains four polar covalent bonds between carbon and hydrogen atoms. However, the overall molecule is nonpolar due to its symmetrical tetrahedral shape, which cancels out the individual bond dipoles.
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.
