Which is a secant of circle A?
sergey [27]

Answer: line CD (fourth choice)

====================================================

Let's go through the choices one by one

1) Segment AB is a radius, which is not a secant line. We can rule this out.

2) line DE is a tangent line which only touches the circle at exactly one spot. We need something that cuts the circle in 2 spots for it to be a secant line. This can also be crossed off the list.

3) segment HG is a chord, which is fairly close to a secant line, but it must extend infinitely in both directions. In other words, it needs to be a line instead of a line segment. This is crossed off the list.

4) line CD is a secant line. It is a geometric line in that it goes on forever in both directions (it's not a segment, and not a ray either). Also, this line crosses the circle at 2 points, which contrasts it from a tangent line. This is the answer we want.

Subtract: write each in simplest form. 1/2-1/4=
Zepler [3.9K]

1/2-1/4

Find its LCM which would be 4

So change the 1/2 to 2/4 and keep 1/4 the same since we already have the denominator we need so

2/4-1/4 = 1/4
