Sep 19, 2022 · Every (non-empty, non-tangential) intersection of a plane and a sphere is a circle. The circle is great if its Euclidean radius is equal to the radius of the sphere, i.e., if the plane of intersection contains the center of the sphere, and is small otherwise. In spherical geometry, great circles are sometimes called (straight) lines while small ...
e. In geometry, a straight line, usually abbreviated line, is an infinitely long object with no width, depth, or curvature, an idealization of such physical objects as a straightedge, a taut string, or a ray of light. Lines are spaces of dimension one, which may be embedded in spaces of dimension two, three, or higher.
An old name for the line is the right line 1). When the center of inversion is not on the line, the inverse of the line is a circle. And the line is the pedal of the parabola. The straight line stands for a linear relation, a linear relationship between two variables. In nature there are a lot of phenomena which are related in a linear way.
Sep 30, 2024 · Curved Line. Curved Line is a group of collinear points with curvature or bends in its configuration. For example, curve line can be seen in the meandering course of a river. Oblique or Slanting Line. Oblique or Slanting Lines are lines drawn in a slanting position, forming angles other than 0, 90, 180, 270, or 360 degrees with horizontal or ...

The part of a straight line between two points is called a line segment. In the figure look at the points A and B. A straight line is passing through but only the part of line lying between A and B is line segment. A line segment has two end points. It's length can be measured.
A straight line is a figure formed when two points A (x 1, y 1) and B (x 2, y 2) are connected with the shortest distance between them, and the line ends are extended to infinity. In the image shown below, a straight line between two points A and B is shown. A straight line AB is represented by: ←→ AB A B ↔.

Oct 4, 2024 · To compute the equation of the line passing through points (x1, y1) and (x2, y2): Compute the slope as a = (y2-y1) / (x2-x1). Compute the intercept as b = y1 - a × x1. The equation you need reads y = a × x + b, with a an b computed as above. If x2 = x1, you cannot compute a — the line is vertical and has equation x = x1.
