Okay, kiddo. Let me explain what a limiting point is in geometry.
Imagine you are standing in a big field full of trees. You start walking around in a circle, and as you keep walking, you start noticing that some trees are getting closer and closer to you. These trees become what we call "limiting points".
In geometry, a limiting point is a point that "approaches" another point or set of points, but never actually touches it. It's like if you were crawling towards a toy on the floor, but you never reach it, and you keep getting closer and closer.
For example, let's say we have a line that goes on forever in both directions. If we pick a point on that line and draw a circle around it, we'll see that there are points inside the circle that are also on the line. As we make the circle bigger and bigger, eventually we'll get to a point where the circle touches the line at only one point. This point is a limiting point, because it's not inside the circle, but it's as close as we can get to being inside the circle.
Does that make sense, kiddo?
