Tetrahedral and trigonal pyramidal have the same electron structure: 4 electron density regions surrounding a central molecule) but they have different molecular structures. For tetrahedral there are 4 electron density regions around the central atom that consist of 4 different atoms. In trigonal byramidal there are three surrounding atoms and a lone pair.
A molecule has a tetrahedral shape when the central atom is bonded to four atoms and has no lone pairs (bond angle is 109.5 degrees). A trigonal pyramidal molecule has a central atom that has one lone pair and is bonded to three atoms (the lone pair causes repulsion, causing the angle to be slightly less than 109.5 degrees).
