Punkte, Linien und Ebenen
Verstehen grundlegender geometrischer Konzepte: Punkte, Linien und Ebenen
Interactive Points, Lines, and Planes Visualization
Introduction
Explore fundamental geometric concepts in 2D coordinate space. Points represent locations, lines connect points, and you can visualize different types of lines.
Features:
- Points: Create points in 2D space and see their (x, y) coordinates
- Line Segments: Connect two points with a finite line segment
- Rays: Draw rays that extend infinitely in one direction from a starting point
- Lines: Create infinite lines extending in both directions
- Coordinate System: Visualize points and lines on a 2D Cartesian coordinate plane
- Interactive Grid: Toggle grid, axes, and labels for better visualization
How to Use
- Points: Enter X and Y coordinates and click "Add Point" to create a point on the coordinate plane
- Lines: Create at least 2 points, then select line type (segment, ray, or line) and choose start/end points from dropdowns
- Click to Add: Click directly on the canvas to add points at that location
- Selection: Click on a point in the list to highlight it on the canvas
- Toggle Options: Use checkboxes to show/hide grid, axes, and labels
- Clear: Use "Clear All" to remove all points and lines, or "Remove Last Point" to remove the most recent point

Instructions
- Points: Enter X, Y coordinates and click "Add Point"
- Lines: Create at least 2 points, then select line type and choose start/end points from dropdowns (or leave empty to use last 2 points)
- Selection: Click on a point in the list to highlight it in the 2D view
- Coordinates: Points are positioned at the exact coordinates you specify (X, Y)
- Coordinate System: X-axis is horizontal, Y-axis is vertical, origin (0,0) is at the center
