What is a chord of a circle that goes through the center of a circle?
It is the circle's diameter
What is a cord that goes through the center of a circle?
A chord that passes through the center of a circle is its diameter.
Is a chord always equal to the length of the diameter?
No; actually, the diameter is a chord that goes through the center of a circle.
What is a line that goes through a circle from top to bottom?
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 chord of that circle. If the chord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest chord of the circle.
Is a diameter the same as a chord?
Hey,Yes and no.A chord is any straight line that starts and ends on the circle. If a chord goes through the center of the circle then it is a diameter.Hope this helps,Toby
