The distance of a point from the y-axis is called its x-coordinate, or abscissa.The distance of a point from the x-axis is called its y-coordinate, or ordinate.The coordinates of a point on the x-axis are of the form

irp-cdn.multiscreensite.com12. COORDINATE GEOMETRY THE CARTESIAN PLANE We recall from our study of plane geometry that a plane is a two-dimensional region. We now wish to describe the position of a point on a plane. To do so, we use the Cartesian Coordinate system. The plane consists of a horizontal number-line called the x-axis, and a vertical number-line called the y-axis

Prove by coordinate geometry that ABC is an isosceles right triangle. 2. Given ABC with vertices A(-4,2), B(4,4) and C(2,-6), the midpoints of AB and BC are P and Q, respectively, and PQ is drawn. Prove by coordinate geometry: a.

people.math.wisc.eduThe reduction of geometry to algebra requires the notion of a transfor-mation group. The transformation group supplies two essential ingredients. First it is used to de ne the notion of equivalence in the geometry in question. For example, in Euclidean geometry, two triangles are congruent i there is

amsi.org.auCoordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.
