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 WhatsHalfway.com, 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 distanceÂ 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 »

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 »

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 »

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 »
