FAQs on Coordinate Geometry Video Lecture - Crash Course: Class 10

1. What is coordinate geometry in class 10?
Ans. Coordinate geometry is a branch of mathematics that deals with the study of geometric figures using a coordinate system. It involves representing points, lines, curves, and shapes in a plane using numerical values called coordinates.
2. How is coordinate geometry useful in real life?
Ans. Coordinate geometry has several real-life applications. It is used in navigation systems to determine the location of a vehicle, in computer graphics to create images and animations, in architecture and engineering for designing structures, and in physics and astronomy to study the motion of objects.
3. What are the basic concepts of coordinate geometry?
Ans. The basic concepts of coordinate geometry include the Cartesian coordinate system, which consists of a pair of perpendicular lines (x-axis and y-axis) intersecting at a point called the origin. Points in the plane are represented by ordered pairs (x, y), where x represents the horizontal distance and y represents the vertical distance.
4. How do you find the distance between two points in coordinate geometry?
Ans. The distance between two points (x1, y1) and (x2, y2) in coordinate geometry can be found using the distance formula. The formula is √[(x2 - x1)^2 + (y2 - y1)^2]. By substituting the coordinates of the given points into the formula, we can calculate the distance between them.
5. What are the different types of slopes in coordinate geometry?
Ans. In coordinate geometry, there are three types of slopes: positive slope, negative slope, and undefined slope. A positive slope indicates an upward direction, a negative slope indicates a downward direction, and an undefined slope occurs when a line is vertical. The slope of a line can be calculated using the formula (change in y)/(change in x).
