The verb agrees with the subject in the statement "The sides of an Egyptian pyramid are almost exactly equal."
In English, the verb only needs to match the number and occasionally the person; subject-verb agreement is a grammar rule that states that the verb or verbs in a phrase must match the number, person, and gender of the subject. English does not utilize grammatical gender (apart from pronouns) and only the verb be alters depending on whether it is in the first, second, or third person. This is known as subject-verb agreement, also known as "subject-verb concord." Accordingly, the majority of subject-verb agreements in English are quantified: if the subject is singular, the verb must also be singular; if the subject is plural, the verb must also be many.
