Which of the following is two-dimensional and infinitely large? A. Geometric space B. A plane C. A line D. Two rays

The correct answer is B: A plane. A plane is a flat, two-dimensional surface that extends infinitely in all directions, much like an endless piece of paper that has no edges! It’s essential in geometry and serves as a foundational concept in various branches of mathematics, making it an exciting topic to dive into. When working with planes, one common mistake is assuming they have boundaries, but keep in mind that a plane is indeed infinite. A fun tip to avoid confusion is to visualize a piece of graph paper extending beyond your computer screen—every point on that grid theoretically exists infinitely in that plane!
