Diameter runs straight across. Radius only goes half way, to the center.
Radius
all you have to do is find a line with two endpoints on the circle also a diameter is the longest chord on a circle that runs through the middle of the circle.
A line that does not touch the circumference of a circle is called a "secant" if it intersects the circle at two points, or an "external tangent" if it runs parallel to the circle without intersection. However, if the line is entirely outside the circle and does not intersect it, it is simply referred to as a "non-intersecting line" or "external line." In contrast, if a line touches the circumference at exactly one point, it is called a "tangent."
This is a straight line, runs through the origin and has a slope of 12.
A horizontal line is a straight line that runs parallel to the x-axis in a Cartesian coordinate system. It has a constant y-coordinate, meaning that every point on the line has the same vertical position. As a result, it does not rise or fall, remaining level across its length. In mathematical terms, a horizontal line can be represented by the equation ( y = c ), where ( c ) is a constant.
the arctic circle is at 66.5oN, while the antarctic circle is at 66.5oS

A chord is a straight line within a circle that divides the circle into two parts - these parts are called arcs.The diameter is a chord that runs through the centre of the circle and divides the circle into two equal parts.

A line of latitude that runs through Antarctica is 66.5 degrees. The Antarctic Circle is the South region that includes the South Pole and the Antarctic Circle.
The Arctic Circle.
Arctic Circle
The line of latitude that runs through the north of Iceland is the Arctic Circle, which is at approximately 66.5 degrees north latitude.

* The Antarctic Circle cuts across the coastal regions of the Antarctic continent at several points. * The Arctic Circle runs through Asia, Europe and North America.
The equator!!!
Horizontal lines are straight curves that typically runs from left to right across the page, usually sharing the same y-coordinate. Horizontal lines are perpendicular to vertical lines.
