Step-by-step explanation:
The performance configuration that has the audience on just one side of the stage is called a proscenium theatre. In a proscenium theatre, the stage directly faces the audience, and the stage is framed with a proscenium arch that creates a window through which the audience experiences the production.
This configuration highlights the division between actors and the audience, with the audience on one side and the actors performing on the other side.
