Final answer:
The consonant phonemes /th/ and /th/ are created with the place of articulation known as interdental and the manner of articulation known as fricative.
Step-by-step explanation:
The consonant phonemes /th/ and /th/ are created with the place of articulation known as interdental. This means that the tip of the tongue is placed between the upper and lower front teeth to produce these sounds. The manner of articulation for these phonemes is fricative, which means that the airflow is partially obstructed, creating friction as the air passes through the narrow space between the tongue and teeth.
