Analyze the provided image and identify the geometric shapes and points depicted.

Image Analysis:

• The image depicts a circle.
• There are three points marked with blue circles on the circumference of the circle.
• There is one point marked with a blue circle inside the circle, approximately at the center.
• Two lines are drawn connecting points on the circumference. One line appears to be a chord, and the other connects two points on the circumference and passes through the internal point.
• A letter 'X' is present inside the circle, near one of the points on the circumference.
• The geometry suggests a diagram related to circle properties, possibly involving chords, diameters, or inscribed angles.
