Explanation:

#sp^2# hybridization results from averaging out three orbitals 1 s orbital and 2 p orbitals.

This results in three equivalent orbitals.

An example is Aluminum #Al#. Aluminum number 13 has three valance electrons 2 s and 1 p. in the third electron shell. By elevating one electron in the s orbital to a second p orbital Aluminum has three orbitals that can be hybridized.

The result is three equivalent orbitals. This can be seen in that Aluminum forms compounds like #AlCl_3# in a planar triangular form. In the triangular planar geometry there are three equivalent bonds all at the same angle.
