Explanation:

And thus to a first approximation it is "trigonal pyramidal"trigonal pyramidal.

The experimental /_H-P-H=93.5^@∠H−P−H=93.5∘, which is SMALLER than the corresponding angle in ammonia, /_H-N-H=105^@∠H−N−H=105∘, and hard to rationalize on simple grounds of VESPER. You should buttonhole your prof for his rationale. (And repost his account here!)
