Lets understand what is meant by bond angle for the better understanding of the question. Bond angle is the angle between the two bonds which originates from the common atom. Molecular geometry is the three dimensional arrangement of atoms in a molecule. It includes the shape of the molecule, the bond length and the bond angle and any other geometric parameters. The geometry of $B{{F}_{3}}$ is a trigonal planar in which the fluorine atoms lie in the same plane and have a bond angle of around 120 degree. The bond angle in $P{{F}_{3}}$ is 109 degree because there are lone pairs at the top of the molecule and the shape of the molecule is trigonal pyramidal. And the bond angle in $Cl{{F}_{3}}$ is 90 degree due to the presence of lone pairs in the molecule and the shape of the molecule is T shaped.
