What is a straight line joining any 2 points on an arc or curve or circle?
If the straight line crosses two points of a circle and goes through the center of the same circle it is the diameter. If these conditions are not met it is a chord.
What is the straight line through the center of 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.
What is a line segment with endpoints on a circle better known as?
A chord. The diameter is technically a chord goes through the middle point.
What is a chord of a circle that goes through the center of a circle?
It is the circle's diameter
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
