The molecule of iodine heptafluoride has a bi-pyramidal pentagonal shape. All of the F-I-F angles between two fluorine atoms in axial and equatorial planes are equivalent to 90 degrees. Therefore there is five of them.
7 angle of 90
10
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
3 electron groups classified as trigonal planar. The molecular geometry is Angular or Bent whichever you prefer to call the shape. The ideal bond angles are 120 degrees and the molecule is polar.

I am not 100% sure about this, but I have found many reports that the CO2 compound has a bond angle of 180 degrees,and many chemistry sites support 180 degrees.
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.
