How do you know that the diameter in a circle is the longest possible chord in the circle?
Because it is a line through the center of the circle and it is impossible for a line that is not through the center to be longer than one that is through the center.
What is the interior of a circle?
The set points whose distance from the center of the circle that is less than the radius. A disk.
What is a cord that is drawn from the center of a circle?
A cord that crosses the center of a circle is a diameter, which divides the circle into two equal halves. It is a line segment, and it is the longest cord that can be drawn within a circle.However, if the segment begins at the center rather than crosses through it, and has the other endpoint on the circumference of the circle, it is not a cord, but is a radius of that circle.
Is a circle less than or equal to the radius?
The radius of a circle is the distance from the center of the circle, out to the edge of the circle. The distance all the way across the circle is the "diameter." Half of the diameter is the radius.
What is the line that joins two points on the circle?
That's a 'chord' of the circle.If it passes through the center of the circle, then it's also called a 'diameter'of the circle, and no other chord of that circle can be longer than it is.
