Question

why do we need to have a naming convention for angles? then we know who their parents are! it tells us how big they are. to make sure that everyone knows which angle we are talking about.

Explanation:

A naming convention for angles helps in clear communication. It allows everyone to know exactly which angle is being referred to, especially in complex geometric figures with multiple angles. Just like we need names to identify people, naming angles helps in precision in mathematics - stating which two - ray combination forms the angle and its position relative to other elements in the figure.

Answer:

To ensure clear communication and precision about which angle is being discussed, especially in complex geometric set - ups with multiple angles.
