Question

Part A: Parallel lines are two lines that never meet. Find an example that contradicts this definition. How would you change the definition to make it more accurate? (5 points)
Part B: Give an example of an undefined term and how it relates to parallel lines. (5 points)

Answer 1

The answers to the given questions are explained below as required:

Part A: Parallel lines are two lines that do not meet. So that the two lines are at an angle of $180^{o}$ to each other.

ii. A good example that contradicts the definition of parallel lines is the perpendicular lines. Two lines are said to be perpendicular if and only if they are at right angle to each other. Thus, the two lines would be at an angle of $90^{o}$ to one another.

iii. The definition that would be more accurate is: parallel lines are two lines that do not meet, even when extended till infinity.

Pat B: Undefined terms are terms that can be simply explained by descriptions. Some of the terms are: lines, rays, points etc.

ii. Lines can be used appropriately to illustrate parallel lines.
