Coordinates of a point - Math Open ReferenceThe coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located.
Distance from a point to a line using line equations; Distance from a point to a line using trigonometry; Distance from a point to a line using a formula; Limitations. In the interest of clarity in the applet above, the coordinates are rounded off to integers and the lengths rounded to one decimal place. This can cause calculatioons to be ...

In another branch of mathematics called coordinate geometry, points are located on the plane using their coordinates - two numbers that show where the point is positioned. To achieve this, the plane is thought to have two scales at right angles. Using a pair of numbers, any point on the plane can be uniquely described. For more on this, see
A method of calculating the area of a polygon given the coordinates of each vertex. Math Open Reference. Home Contact About Subject Index. Algorithm to find the area of a polygon. If you know the coordinates of the vertices of a polygon, this algorithm can be used to find the area. Parameters. X, Y : Arrays of the x and y coordinates of the vertices, traced in a clockwise direction, starting ...
Recall that the incenter of a triangle is the point where the triangle's three angle bisectors intersect. It is also the center of the triangle's incircle. The coordinates of the incenter are the weighted average of the coordinates of the vertices, where the weights are the lengths of the corresponding sides. The formula first requires you calculate the three side lengths of the triangle.
Try this Drag the point A or B. As you drag, the length of the line segment linking them is continuously recalculated. The formula above can be used to find the distance between two points when you know the coordinates of the points. This distance is also the length of the line segment linking the two points. This formula is simply a use of Pythagoras' Theorem. In the figure above, click ...

Coordinates of a Point | Abscissa or X-coordinate | Ordinate or Y ...How to determine coordinates of a point? On a graph paper draw X'OX and YOY'. Here X'OX and YOY’ be the two coordinate axes. Then mark a point on the graph and name the point as P such that P is at the perpendicular distance of a units from the y-axis and again similarly b units from the x-axis.
