Answer:
Absolute
Prepositional
Participial
Explanation:
A subordinate CLAUSE (not phrase) contains a subject and verb, is introduced by a conjunction, and supports the main clause.
An absolute phrase combines a noun and a participle. (e.g. shining stars, crossed arms)
A prepositional phrase is a modifying phrase consisting of a preposition and its object. (on the table, beside the stairs)
A participial phrase will begin with a present or past participle and will always function as an adjective, describing a nearby noun or pronoun.
(e.g. PUTTING ON HER BOOTS, she trudged into the snow.)
