What is a line through a circle called?
A line that goes through a circle is a secant line. (Remember that a line is infinitely long.) Anyline that passes through a circle is a secant line, whether it passes through the center of the circle or not. Compare this to a line segment with endpoints on the circumference of a circle. That segment is called a cord of that circle. If the cord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest cord of the circle.
Is the circle or straight line symbol on or off?
The line stands for "on" and the circle stands for "off".
Can the chord of any circle or oval be rounded like the outer edge of the circle or oval?
No, it cannot. A chord of a circle is a line segmentwhich has its endpoints on the curve (or circumference) of the circle. A line segment is part of a line, and a line is straight. It's that simple.
The point where the tangent line intersects a circle?
A tangent line touches the circumference of a circle at just one point but it does not intersect the circle.
How do you find the radious of a circle?
The radius of a circle is any straight line from the centre of the circle to its circumference. The radius can also refer to the length of this line.
