A circle in geometry is a shape that we can draw on a flat surface.
Imagine a central point right in the middle of the circle.
Every point on the edge of the circle is the same distance from this center point.
This distance is called the radius.
Diameter: This is the longest line you can draw across the circle. It goes from one side of the circle to the other, passing through the center. The diameter is twice the length of the radius. (So, if the radius is 3, the diameter will be 6!)
Chord: This is a straight line that connects two points on the circle.
Tangent: This is a straight line that just touches the circle at one point. It doesn’t go inside the circle at all.
Secant: This is a line that cuts through the circle, hitting it at two different points.
Knowing these terms can really help you understand and work with circles better!
