Detailed explanation-1: -For example; four electron pairs are distributed in a tetrahedral shape. If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4).

Detailed explanation-2: -In methane molecule, the carbon atom forms covalent bonds with four different hydrogen atoms. There are no lone pairs on carbon atom. Therefore, the four hydrogen atoms are arranged at four corners of tetrahedron and carbon at the centre of the tetrahedron. The structure of methane molecule is tetrahedral.

Detailed explanation-3: -The shape of methane That is a tetrahedral arrangement, with an angle of 109.5°. Nothing changes in terms of the shape when the hydrogen atoms combine with the carbon, and so the methane molecule is also tetrahedral with 109.5° bond angles.

Detailed explanation-4: -In methane the four electrons of carbon bind with the four electrons of four hydrogen atoms to form four covalent bonds. In methane carbon atoms are bonded with four hydrogen atoms. The structure of the methane is shown below. Thus, methane with the molecular formula $CH 4$ has 4 covalent bonds.
