Concyclic

When we talk about points or shapes being concyclic, it means that they are all sitting on the same circle. It's like when you and your friends sit together on the swings in a circle - you are all sitting on the same swing set!

For example, if we have four points A, B, C, and D, and they all sit on a circle, then we say that these points are concyclic. This means that they all share the same curved line around them.

When we draw a curve that goes through all the points, we call it the "circumference" of the circle. This circumference is like a border that connects all the points together in a nice circle shape.

So, if you see the word "concyclic" in math or geometry, you can think of it like friends sitting in a swing set circle or dots sitting on a circle line. They're all connected by the same shape, and they're all part of that shape together.
