Sep 12, 2020 · Two curves are parallel if at any point you draw a line perpendicular to the tangent line and passes through the point of tangency (the normal line), the normal lines are all parallel, at any point along the curve, and the distance between the line's points of intersections with the two curves are all the same.
In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
Aug 12, 2022 · Two points on a plane determine a line. A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry, all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.
Most of the three-dimensional shapes can be defined as a set of vertices, lines that connect the vertices and faces enclosed by these lines including obtained interior points. For many three dimensional shapes, faces are two-dimensional. Also, some shapes in three dimensions have curves surfaces.

In basic geometry, fundamental concepts like points, lines, and planes form the foundation upon which more complex geometric ideas are built. Points are precise locations in space, devoid of size or dimension, represented simply by dots. Lines are infinite paths stretching in two opposite directions, composed of an unending series of points. They a...
A Point in geometry is defined as a location in the space that is uniquely determined by an ordered triplet (x, y, z) where x, y, & z are the distances of the point from the X-axis, Y-axis, and Z-axis respectively in the 3-Dimensions and is defined by ordered pair (x, y) in the 2-Dimensions where, x and y are the distances of the point from the X-a...
When 3 or more points are present on the straight line then such types of points as known as Collinear pointsand if these points do not present on the same line, then such types of points are known as non-collinear points.
When the group of points is present on the same plane then such types of points are known as coplanar points and if these points do not present on the same plane, then such types of points are known as non-coplanar points.
A Line in three-dimensional geometry is defined as a set of points in 3D that extends infinitely in both directions It is the smallest distance between any two points either in 2-D or 3-D space. We represent a line with L and in 3-D space, a line is given using the equation, In 3D we can also form a line by the intersection of two non-parallel plan...
A line segment is defined as the finite length of the line that is used to join two points in 2-D and 3-D. It is the shortest distance between two points. A line segment between two points A and B is denoted as, AB A line has infinite length whereas a line segment is a part of a line and has finite length.
Midpointis defined as the point on the line segment which divides the line segment into two equal parts. Suppose we have two points A and B and the line segment joining these two points is AB and not the point P on the line is called the midpoint if it breaks the line into two equal parts such that, AP = PB Thus, P is called the midpoint of line se...
A ray is defined as a line that has a fixed end point in one direction but can be extended to infinity in the other direction. It is of infinite length. We define the ray joining points O and A and extending to infinity towards A as
In 2-D any two lines can either meet at some point or they never meet at some point. The lines that meet at some point are called intersecting lines. The distance between the intersecting line keeps on decreasing as we move toward the point of intersection, and at the point of intersection of these lines, the distance between them becomes zero. Whe...
Intersecting lines that intersect at right angles are called perpendicular lines. The angle between theseperpendicular linesis always the right angle or 90 degrees. The perpendicular lines are shown in the image added below:

Aug 16, 2024 · Two-dimensional (2D) shapes are flat figures that have only length and width, but no depth. They exist solely on a plane, meaning they are confined to two dimensions and do not have any thickness. These shapes can be geometrically defined by points, lines, curves, and angles that form closed boundaries.
