Bond Angle and Terminal Atoms

[SavannahScriven_1F]

If there is a molecule with a trigonal planar shape, but one of its terminal atoms is larger than the other two, this would affect the bond angles. Would we still say it's 120 or would we say it's <120 (or greater than, depending on which bond angle is specified)? Would a multiple choice question ever make us choose between 120 and <120 in cases like these?

Yes the larger atom does have a small effect.
Question would make it clear what is being asked.

it would only be a small effect because the larger atom is obviously larger and would take up more space in the planes, but the difference wouldnt be too substantial.
