FAQs on Co-ordinate geometry - 2 Video Lecture - Crash Course for UGC NET Economics

1. What is co-ordinate geometry?
Ans. Co-ordinate geometry is a branch of mathematics that deals with geometric figures using a coordinate system. It involves studying shapes, sizes, and relative positions of objects using algebraic equations.
2. How is the distance between two points calculated in co-ordinate geometry?
Ans. The distance between two points (x1, y1) and (x2, y2) in co-ordinate geometry is calculated using the distance formula: √((x2 - x1)^2 + (y2 - y1)^2).
3. What is the equation of a line in co-ordinate geometry?
Ans. The equation of a line in co-ordinate geometry is typically represented in the form y = mx + c, where m is the slope of the line and c is the y-intercept.
4. How are parallel and perpendicular lines identified in co-ordinate geometry?
Ans. Parallel lines have the same slope, while perpendicular lines have negative reciprocal slopes. By analyzing the slopes of the lines, one can determine if they are parallel or perpendicular in co-ordinate geometry.
5. How is the midpoint of a line segment calculated in co-ordinate geometry?
Ans. The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is calculated by taking the average of the x-coordinates and the average of the y-coordinates, resulting in ((x1 + x2)/2, (y1 + y2)/2).
