Here, ray OC, ray OA, and ray OG originate from the point O. Solution: Ray OC, ray OA, ray OG, ray CA, and ray GS are five rays seen in the given figure. These rays start from point G and proceed in the opposite direction to form a straight angle.Įxample 3: Write the names of any five rays as seen in the given figure. Solution: Ray GH and ray GC are opposite rays in the given figure. Since the origin point of a ray is called its endpoint, here G is the endpoint.Įxample 2: Which rays are opposite to each other in the figure below? Solution: In the given figure, the endpoint of ray GF is G. Solved ExamplesĮxample 1: What is the endpoint of ray GF in the given figure below? It helps us understand the concept of angles and multiple angles enable us to form a polygon. Having a clear idea about a ray in math is important.

  • The name of a ray must always include its origin point.

  • A ray is a geometric figure that has no height or width.
  • In the below figure, the angle ABC is formed by the rays BA and BC. It is the vertex that gives us the measure of an angle. The vertex of the angles is the starting point of the rays. Here, in the below figure, each of the angles is made up of two rays. In geometry, when two rays share a common endpoint, they form an angle. You can name it ray DE or ray DF.įun Fact: The point from where a ray starts its journey towards infinity is called its endpoint! Rays and Angles It has a ray that passes through two points on its endless journey. Here, the starting point of ray PQ is P, and on its way to infinity, it passes through point Q. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray. So, the first letter of a ray’s name indicates its starting point. A ray is named using its initial point and any other point through which it passes. I graduated from Mary Hardin-Baylor with a Bachelor of Science degree in Education with a. On its way to infinity, a ray may pass through more than one point. I am presently teaching Geometry here at East View High School. The sun is the starting point or the point of origin, and its rays of light extend indefinitely in our solar system. Since a ray has no end point, we can’t measure its length.įun Facts: The sun rays are an example of a ray. It can extend infinitely in one direction. The definition of ray in math is that it is a part of a line that has a fixed starting point but no endpoint. Come, let’s begin! What Is a Ray in Math?

    Today, we shall find out what a ray is in math. Rays help us form different angles depending on how we arrange them. To structure an angle, we need to know what a ray is in math. We come across various angles in our everyday life, such as the hands of a clock, a slice of pizza, and an arrowhead showing direction, to name a few.
