👉 In mathematics, a "crisscrossed" object is an object that can be represented by two lines or curves intersecting at right angles. These objects are also called "crossed" or "cutting" objects. For example, a "crisscrossed line" (also known as a "crossed curve") would represent a straight line in three dimensions but with its endpoints cut off by a plane. Similarly, a "crisscrossed surface" would be defined by two
