Answer:
The correct answer for this is : A. Point and Line
Step-by-step explanation:
The lines are said to be parallel to each other if they do not intersect each other at any point. So, for any number of lines to be parallel we must have lines and no intersection points between them then only we can say the given number of lines are parallel to each other
So, the terms which are used to explain the term parallel lines here are : line and the point.
And the both terms point and a line are undefined in the geometry.
Hence, the correct answer for this is : A. Point and Line
The pair of undefined terms are used to define the term parallel lines are point and line. Option A. This is further explained below.
Generally, parallel lines are simply defined as Two lines in the same plane that are always exactly the same distance apart and are said to be parallel.
In conclusion, If there is no point at which the lines meet, then we say that they are parallel to one another. Therefore, in order to state that a particular set of lines is a set of parallel lines, we must first establish that there is a set of lines with no junction points.

Step-by-step explanation
PEMDAS
3. Indicate whether each of the three reciprocal functions (cosecant, secant, and cotangent) is a periodic function. If so, state the period of each.
4. List the domain and range for the secant and cotangent functions. (Use "pi" for π.)
5. Compare the graphs of the cosecant and secant functions. How are they different? How are they similar?
Step-by-step explanation:
1. All the trigonometric values can be found using the unit circle. See attached table.
2. Graph:

3. All trig functions are periodic functions. The period of secant and cosecant is 2π. The period of cotangent is π.
4. Using the table from step 1 and the graph from step 2, secant has a domain of x ≠ pi/2, 3pi/2 and a range of x ≤ -1, x ≥ 1. Cotangent has a domain of x ≠ 0, pi, 2pi and a range of -∞ < x < ∞.
5. Graph:

Cosecant has the same graph as secant shifted π/2 to the right. So they have different domains, but the same range.
