Explain the shape of $sp$,$sp^2$,and $sp^3$ hybrid orbitals.

(N/A) $sp$ orbital: The two $sp$ hybrid orbitals are oriented in opposite directions along a straight line with an angle of $180^{\circ}$ between them.
$sp^2$ orbital: These three $sp^2$ hybrid orbitals are oriented in a trigonal planar arrangement,symmetrically at an angle of $120^{\circ}$ between them.
$sp^3$ hybridization: The four $sp^3$ hybrid orbitals are directed towards the four corners of a regular tetrahedron. The angle between any two $sp^3$ hybrid orbitals is $109^{\circ} 28^{\prime}$.
