Point – a point has only one position and no particular dimension.

There are a few simple terms that make you understand the concept of geometry well. You can measure the segment but not a line. On the other hand, a segment has two endpoints and doesn’t extend in only one direction. You can mark any two points in a line and define them the same. They are not affected by the earth’s gravity, so they always travel in a straight line.Ī line is infinite in both directions, unlike a ray. Lasers are perfect examples to understand what rays are. These are some day to day examples you see around.

A similar example is seen for a movie projector in a cinema hall. An LED light beam from a classroom projector is an example of a ray.Rafael Nadal, the famous tennis player, serves his tennis ball at 217 kph, which defies gravity’s tug, and hence it travels in a straight line, just like a ray.The rays extend in one direction infinitely. Why do we call it sun rays and not sun lines? It is because, unlike lines, rays do not have an endpoint. One of the most famous examples of a ray is sunlight, which originates from the sun and goes in one direction if it is not blocked.To symbolize a ray, we identify two points on it and then write it as -> RN. Use a scale to draw a straight line from your starting point and continue it to your second point.ĭraw an arrowhead to the open side of the line. To draw a ray, place two points on a page and label them both with capital letters. Hence, you see one angle is made of two rays. The vertex of these angles is the starting point of these rays. A ray can pass through more than one point. In geometry, a ray can be defined as part of a line that has a beginning point but no endpoint. The syllabus for geometry is generally divided into two halves – Plane Geometry and Solid Geometry. This branch of mathematics helps you to measure both 2D and 3D shapes that you see around.

Geometry deals with shapes, sizes, positions, angles, dimensions of different things. Later in the 19th-century, geometry saw a considerable discovery when Gauss’s theorem was introduced that students learn in their higher studies now. Until the 19th-century, geometry was called Euclidean Geometry that had concepts of line, point, plane, distance, angle, surface, and curve. Geometry is one of the oldest branches of mathematics that has been taught to students for centuries. It is also the easiest as compared to other topics of mathematics. It is one of the most exciting branches of mathematics which children love to learn. Geometry is a subject that students have been learning in bits and pieces since 1st grade.
