Arabic has the following demonstrative pronouns/adjectives (this, that, these, those), these words agree with the noun they apply to in number (as in English) but also in gender. "this/these" also has a dual form which also has to agree in gender with the noun it applies to. "that/those" technically also has a dual form but it is very rarely used, so it will be omitted:
