Is a point the chord of a circle?
No, it is not. A chord is a line segment. It cannot have a length of zero. A point has no dimensions. The chord of a circle is a line segment that has its endpoints (both of them) on the curve (or circumference) of the circle.
The Koch Curve has a finite length?
false
Why successive lines with a change in slope look like a curve?
A curve is formed by lines. If the length of these lines is reduced to zero, we get a very smooth curve.
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.
What is tangent line?
tan A = (sin A) / (cos A) tan (A)= opposite side length/adjacent side length A is an angle measurement; amount of degrees or radians. If a line is tangent to a curve, it only touches the curve at one point. looks like )| but the line is touching the curve. In a circle, the tangent line touches the circle at one point and is perpinducular to the circle's radius if it is touching that same point.
