Placements that square one another create tension that can be irritating or activating.
Square or Opposition: If placements are the same modality, they'll either be square or opposite one another. Signs that are three signs apart are square, while signs that are six signs apart are in opposition. For example, if you have your Mercury in Gemini and rising in Virgo — two mutable signs — they square one another. If your Mercury is in Capricorn but your rising is in Cancer, that's an opposition. Placements that square one another create tension that can be irritating or activating. Placements that oppose one another can be at odds with one another, but if you can work with an opposition's "two sides of the same coin" energy, you can find balance and growth.
