FAQs on Coordinate Geometry Video Lecture - Crash Course for Class 9 (English)
| 1. What is coordinate geometry? |  |
Ans. Coordinate geometry is a branch of mathematics that deals with the study of points, lines, and shapes in a coordinate system. It involves the use of coordinates to represent and analyze geometric figures and their properties.
| 2. How is coordinate geometry used in real life? | |
Ans. Coordinate geometry has various practical applications in real life. It is used in navigation systems to determine the coordinates of a location, in computer graphics to create and manipulate images, in robotics to control the movement of robots, and in architecture and engineering to design and construct buildings and structures.
| 3. What are the main components of a coordinate system? | |
Ans. A coordinate system consists of two perpendicular lines called axes - the x-axis and the y-axis. The point where the axes intersect is called the origin. Each point in the coordinate system is represented by an ordered pair (x, y), where x represents the horizontal distance from the origin along the x-axis and y represents the vertical distance from the origin along the y-axis.
| 4. How do you find the distance between two points in coordinate geometry? | |
Ans. The distance between two points in coordinate geometry can be found using the distance formula. The distance formula states that the distance between two points (x1, y1) and (x2, y2) is given by the square root of [(x2 - x1)^2 + (y2 - y1)^2].
| 5. What is the slope of a line in coordinate geometry? | |
Ans. The slope of a line in coordinate geometry is a measure of its steepness. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line. The slope can be calculated using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
