Geometry Symbols in Maths
In geometry, various symbols are used as a shorthand of some commonly used word. For example ‘⊥’ is used to determine that the lines are perpendicular to each other. Symbols used in geometry are illustrated below:
| Symbol | Name | Meaning | Example |
|---|---|---|---|
∠ | Angle | It is used to mention an angle formed by two rays | ∠PQR = 30° |
∟ | Right angle | It determines the angle formed is right angle i.e. 90° | ∟XYZ = 90° |
. | Point | It describes a location in space. | (a,b,c) it is represented as a coordinate in space by a point. |
→ | Ray | It shows the line has a fixed starting point but no end point. | [Tex]\overrightarrow{\rm AB} [/Tex] is a ray. |
_ | Line Segment | It shows the line has a fixed starting point and a fixed end point. | [Tex]\overline{\rm AB} [/Tex] is a line segment. |
↔ | Line | It shows the line neither has a starting point nor an end point. | [Tex]\overleftrightarrow{\rm AB} [/Tex] is a line. |
[Tex]\frown [/Tex] | Arc | It determines the degree of an arc from a point A to point B. |
[Tex]\frown\over{\rm AB} [/Tex] = 45° |
∥ | Parallel | It shows that lines are parallel to each other. | AB ∥ CD |
∦ | Not parallel | It shows the lines are not parallel. | AB ∦ CD |
⟂ | Perpendicular | It shows that two lines are perpendicular i.e. they intersect each other at 90° | AB ⟂ CD |
[Tex]\not\perp [/Tex] | Not perpendicular | It shows lines are not perpendicular to each other. | [Tex]AB\not\perp CD [/Tex] |
≅ | Congruent | It shows congruency between two shapes, i.e. two shapes are equivalent in shape and size. | △ABC ≅ △XYZ |
~ | Similarity | It shows two shapes are similar to each other i.e. two shapes are similar in shape but not in size. | △ABC ~ △XYZ |
△ | Triangle | It is used to determine a triangular shape. | △ABC, represents ABC is a triangle. |
° | Degree | It is a unit that is used to determine the measurement of an angle. | a = 30° |
rad or c | Radians | 360° = 2πc | |
grad or g | Gradians | 360° = 400g | |
|x-y| | Distance | It is used to determine distance between two points. | | x-y | = 5 |
π | pi constant | It is a predefined constant with value 22/7 or 3.1415926… | 2π= 2 × 22/7 = 44/7 |
Maths Symbols – Basic Mathematics Symbols
Maths symbols are figures or combinations of figures that represent mathematical objects, actions, or relations. They are used to solve mathematical problems quickly and easily.
Foundation of mathematics lies in its symbols and numbers. The symbols in mathematics are used to perform various mathematical operations. The symbols help us to define a relationship between two or more quantities. This article will cover some basic Math symbols along with their descriptions and examples.
