A single bond is a sigma bond. A sigma bond is when 2 orbitals, each with 1 electron, interact end-to-end to form a bond. When two atoms are bound by more than one covalent bond, one of those bonds will be a sigma bond, and the additional bonds will be pi bonds.
Yes, a single bond is a sigma bond. However, when there is a double bond, one of them is a sigma bond and the other is a pi bond. This is because there can only be one sigma bond at a time because it is a bond from end-to-end. Meanwhile, pi bonds are side by side allowing more than one bond at once. Therefore, in a triple bond, one bond is a sigma bond and the other two bonds are pi bonds.
All single bonds will have one sigma bond. However, the other bonds (double and triple) also have sigma bonds. One each. therefore, all double bonds will have one sigma bond and one pi bond, and all triple bonds will have one sigma bond and two pi bonds.
Every covalent bond has one sigma bond and a certain number of pi bonds. Single bonds have 1 sigma and 0 pi bonds, double bonds have 1 sigma and 1 pi bond, and triple bonds have 1 sigma and 2 pi bonds.
Hi! I would remember it like this: Every single bond consists of a sigma bond, every double bond has a sigma bond and a pi bond, every triple bond has a sigma bond and two pi bonds...etc.
Hope it helps!

Every covalent bonding region has a sigma bond. This is to also add that one bond in a double bond is a single bond and the other is sigma. Also, there is no difference rather it describes the character of a single bond. It also can rotate, unlike PI bonds.
A single bond IS a sigma bond! For single through triple bonds they all have one sigma bond, and increase by one pi bond her extra bond starting with a single bond having 0 pi bonds, a double having 1 pi bond, ect.
In order to count sigma bounds, you do have to count the single bonds. So, in a way, single bonds are sigma bonds. However, it's also important to note that sigma bonds also occur in double and triple bonds.
