sp3 hybridization means that the it is a ‘mix’ of 4 completely equivalent molecular orbitals is formed from the 1s and 3p atomic orbitals. It will have tetrahedral geometry.
The theory which describes the relation between number of electron pairs and geometry is called VSEPR: i.e, Valence Shell Electron Pair Repulsion theory.
For two pairs a linear geometry is expected (angle 180 degrees)
For three pairs a planar triangular geometry is expected (angle 120 degrees)
Also for more than four electron pairs VSEPR predicts the electron geometry.
There is one electron pair in each of the 4 orbitals, which will repel each other. The best way to maximize distance between the pairs is when they take vertices of a tetrahedron. And that’s the geometry they will form i.e, tetrahedral (109.5 degrees bond angles).
