Circle and Line Geometry Graph

A clear geometric graph displaying a blue circle centered at the origin of a coordinate system. A red line appears tangent to the circle in the first quadrant. A black line segment, representing the radius, connects the origin to the point of tangency, where a green square visibly marks the right angle formed between the radius and the tangent line.
