Visibility (geometry)
Have you ever played hide-and-seek? Remember when you tried to hide behind a wall so that the seeker couldn't see you? That's kind of like visibility in geometry.
In geometry, visibility means whether or not one thing (like a point or a line) can be seen from another thing (like another point or a line).
Imagine you're standing at Point A and want to see Point B. If there's a wall between you and Point B, you can't see it because it's not visible to you. But if there's no wall, you can see Point B because it's visible to you.
In geometry, we use different tools to figure out if things are visible to each other or not. Sometimes we draw lines or rays to connect points, and if they intersect with something (like a wall), then the points on the other side of the wall are not visible. Other times we might use angles to figure out if something is visible or not.
Overall, visibility in geometry helps us understand how objects in space can be seen from different points of view.
