Definition: A lattice is a geometric shape that has symmetry, and it's composed of straight lines. This means that if you have two parallel lines, they will always be the same distance apart from each other. For example, in a square, the sides are all equal, and when you draw a line segment between opposite corners, it forms a 45-degree angle with the sides. In geometry, latticework is a pattern that consists of rectangles with overlapping sides. It's often used to
