FAQs on MCQ: Coordinate-Geometry - Class 10

1. What is coordinate geometry?
Ans. Coordinate geometry is a branch of mathematics that deals with the study of geometric figures using the principles of algebra. It involves expressing the positions of points on a plane or in space using coordinates, which are pairs or triples of numbers.
2. How are coordinates represented in coordinate geometry?
Ans. In coordinate geometry, coordinates are represented as ordered pairs (x, y) or ordered triples (x, y, z) depending on whether we are working in a two-dimensional or three-dimensional space. The first number represents the horizontal position (x-coordinate), while the second (and third) number represents the vertical position (y-coordinate) and depth (z-coordinate) respectively.
3. What is the distance formula in coordinate geometry?
Ans. The distance formula in coordinate geometry is used to find the distance between two points on a plane or in space. It is derived from the Pythagorean theorem and is given by the formula: Distance = √((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2) where (x1, y1, z1) and (x2, y2, z2) are the coordinates of the two points.
4. How do you find the midpoint of a line segment in coordinate geometry?
Ans. To find the midpoint of a line segment in coordinate geometry, we average the x-coordinates and the y-coordinates of the endpoints. For a line segment with endpoints (x1, y1) and (x2, y2), the midpoint is given by the coordinates: Midpoint = ((x1 + x2)/2, (y1 + y2)/2) This concept can be extended to three dimensions by averaging the x, y, and z coordinates.
5. How is the slope of a line calculated in coordinate geometry?
Ans. The slope of a line in coordinate geometry is a measure of its steepness. It is calculated by taking the difference in the y-coordinates (vertical change) and dividing it by the difference in the x-coordinates (horizontal change). The formula for slope is: Slope = (y2 - y1)/(x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.
