This seems like a misprint. IF6 will have one electron too many to attain an octahedral structure with 90 degree bond angles. SF6 is octahedral, for example, and does have 90 degree angles, as does PF6(-1). Perhaps IF6(+1) is the molecule in question, which will have the proper number of electrons.
76 degrees
Exterior angles: 360 degrees Interior angles: 1620 degrees
Exterior angles: 360 degrees Interior angles: 720 degrees
An isosceles triangle has interior angles of 180 degrees and exterior angles of 360 degrees
The bond angle in carbon dioxide is 180 degrees. This is because it is a linear molecule with two oxygen atoms bonded to a central carbon atom.

SF has a single bond but it is not a molecule.
An isosceles triangle has interior angles of 180 degrees and exterior angles of 360 degrees
all the angles are right angles (90 degrees) and add to 360 degrees
90 degrees per side, 4 angles
A square has 4 right angles. Right angles are 90 degree angles.4*90 degrees = 360 degrees
The interior angles sum to 360 degrees; the exterior angles also sum to 360 degrees.
The interior angles add up to 900 degrees Exterior angles total 360 degrees.
