FAQs on Finding the Distance between Two Points Video Lecture - Quantitative Aptitude (Quant) - CAT

1. What is the formula to find the distance between two points in a coordinate plane?
Answer: The formula to find the distance between two points (x₁, y₁) and (x₂, y₂) in a coordinate plane is given by the distance formula: d = √((x₂ - x₁)² + (y₂ - y₁)²).
2. How can I calculate the distance between two points if only the coordinates are given?
Answer: To calculate the distance between two points (x₁, y₁) and (x₂, y₂) when only the coordinates are given, you can use the distance formula: d = √((x₂ - x₁)² + (y₂ - y₁)²). By substituting the respective values of x₁, y₁, x₂, and y₂ into the formula, you can find the distance.
3. Can the distance between two points be negative?
Answer: No, the distance between two points cannot be negative. Distance is always a positive value representing the length of the line segment connecting the two points. The distance formula involves squaring the differences between coordinates, ensuring a positive result.
4. What units are used to measure the distance between two points?
Answer: The units used to measure the distance between two points depend on the units of the coordinates. For example, if the coordinates are given in meters, the distance will be measured in meters. Similarly, if the coordinates are given in kilometers, the distance will be measured in kilometers.
5. Can the distance between two points ever be zero?
Answer: Yes, the distance between two points can be zero. This occurs when the two points coincide, meaning they have the same coordinates. In this case, the distance between them is considered to be zero as they are essentially the same point.
