A. Classical
Answers and Explanations:
1. Secant line
There are various different kinds of lines in geometry, and each has its own aspects. A secant line is a line that crosses the shape or graph at exactly two points. Here, we can see that line BC crosses circle A at two points: B and C, so we know it's a secant line.
2. Chord
A line segment that connects two points on a circle without crossing the center is called a chord. Now, if the segment <em>had</em> crossed the center, then it would have been called the diameter.
3. Tangent line
As aforementioned, there are different kinds of lines in geometry. Where a secant line has two intersection points, a tangent has only one. Tangent literally means "touching", and we can see from the picture that the line running through point B is "touching" circle A at exactly one point: B.
Hope this helps!
