parallelliset
Parallelliset is the Finnish term commonly used in geometry to describe two or more elements that do not intersect and remain at a constant distance from each other. The concept applies to lines, planes, and other geometric objects that share the same direction.
In a two-dimensional Euclidean plane, two distinct lines are parallel if they never meet. They have the
When a transversal intersects parallel lines, corresponding angles are equal and alternate interior angles are equal
In three-dimensional space, the idea extends to parallel planes: two planes are parallel if their normal vectors
In non-Euclidean geometries, the notion of parallelism can differ. For example, on the surface of a sphere,
Parallelliset are foundational in mathematics and practical activities such as drafting, computer graphics, and civil engineering,
