Given p q q r p. Statements: p, p q, q, q r, r. Statements: ~r, q r, ~q, p q, ~p, p, r. Lines & connerie porque yo no se que este unit was. Point - a dot with no shape or dimension that is used to indicate a specific location. Line - a connection of 2 points that go on forever; 1d ;) Plane - a flat surface made up of 3 points that are noncollinear; 2d: length & width. In geo, parallelograms are used to represent planes. Collinear - when a point belongs on a line with another line. Noncollinear - points that do not belong on the same line. Ray - a line that only goes in one direction; terminates on one side but goes on forever on the other. Line segment addition postulate (lsap) - if a, b, c are collinear. & b is between a & c, then ab + bc = ac.
