What is the Use of Coordinate Plane?Ĭoordinate planes are used for finding the area of larger distances. The XY-coordinate is a two-dimensional plane with coordinate axes, the X-axis and Y-axis, perpendicular to each other. The coordinates of the origin are (0, 0). The point of intersection of two axes of the coordinate plane is the origin of the coordinate plane. What are the Parts of a Coordinate Plane?Ĭoordinate planes include the axes (X-axis and Y-axis), the origin (0,0), and the four quadrants. The coordinate system was invented in the 17th century by the French mathematician René Descartes. These perpendicular lines intersect each other at a point called the origin. Area of Triangle in Coordinate GeometryįAQs on Coordinate Plane What is a Coordinate Plane in Geometry?Ī coordinate plane is a two-dimensional plane formed by the intersection of the x-axis, the horizontal line, and the y-axis, the vertical line.The coordinates of any point are enclosed in brackets.įind out any three points that lie in the positive coordinate plane and for which the abscissa and ordinate are equal and non-negative.The fourth quadrant (+, -) is represented by the Roman numeral IV.The third quadrant (-, -) is represented by the Roman numeral III.The second quadrant (-, +) is represented by the Roman numeral II.The first quadrant (+, +) known as the positive coordinates quadrant, is represented by the Roman numeral I.Also, this is known as the positive coordinate plane as the value of both the coordinates for any point in this quadrant will be positive. Step 4: Mark the point of intersection. ![]()
