There are a variety of gaslighting techniques that an abusive partner might use: Withholding: the abusive partner pretends not to understand or refuses to listen. Ex. Countering: the abusive partner questions the victimâs memory of events, even when the victim remembers them accurately.
If two lines are perpendicular, then they meet to form. right angles. Theorem 1.7.1: If two lines meet to form a right angle, then these lines are perpendicular. âif and only ifâ. âiffâ. Theorem 1.7.2: If two angles are complementary to the same angle (or to. congruent angles) then these angles are congruent.
But when it is perpendicular to two lines (where they intersect) then it is perpendicular to the table: It can't point anywhere else but directly away from the table. So we can say this: When a line is perpendicular to two lines on the plane (where they intersect), it is perpendicular to the plane. It will also be perpendicular to all lines on the plane that intersect there. And there is a lot more we can say:
