In math, the term "distance between two points" refers to the length of a straight line drawn between the two points on an x-y axis. The distance can be determined by finding the change in the y axis and the the x axis a... More »

Use an online website or app, such as MeetWays or, to determine the halfway point between two cities. Both sites allow you to specify whether you wish to stop at a restaurant or other venue when you reac... More »

The distance between two points is calculated using the distance formula d = √ (x2 - x1)2 + (y2 - y1)2, where (x1,y1) and (x2,y2) are the coordinates of the two points and "d" indicates the distance. The distance formul... More » Math Algebra

A chord is a straight line that connects two points on the curve of a circle. Unlike a secant, which is a line that extends infinitely in both directions, a chord is confined to inside the circle. More » Math Geometry

The directrix of a parabola refers to a straight line that is drawn perpendicular to the axis of symmetry of a parabola. This line does not touch the parabola at any point. In addition, it is a horizontal line if the axi... More » Math Geometry

Use the distance formula and a calculator to find the distance between two points. The distance formula works because if two points are plotted on a graph, their direct line is the hypotenuse of a right triangle; thus, t... More »

In math, perimeter is defined as the distance measured around a two dimensional shape. The name originates from the Greek words peri and meter. Peri means around, while meter translates as measure. More » Math Geometry
