Study Notes
Distance Between Points
- The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: √((x2 - x1)^2 + (y2 - y1)^2)
- The distance between points (2, 3) and (4, 1) can be calculated using the formula
- The distance between points (-5, 7) and (-1, 3) can be calculated using the formula
- The distance between points (0, 0) and (36, 15) can be calculated using the formula
Distance Between Towns
- If the distance between towns A and B is 4 km, the coordinates of town A and town B can be calculated using the distance formula
- The coordinates of town A and town B can be represented as (x1, y1) and (x2, y2) respectively
Collinear Points
- Three points (x1, y1), (x2, y2), and (x3, y3) are collinear if the distance between them is 0
- The points (1, 5), (2, 3), and (-2, -11) can be checked for collinearity using the distance formula
