°
Degree
Unit of plane angle measurement. Used for angles, temperature (°C, °F) and geographic coordinates.
∠
Angle
Denotes an angle between two lines or rays in geometry and structural engineering.
⊥
Perpendicular
Indicates that two lines or planes are at 90° to each other.
∥
Parallel
Indicates that two lines or planes never intersect — they run in the same direction.
△
Triangle
Denotes a triangle in geometry. Also used as the change/difference symbol in some contexts.
π
Pi
Ratio of a circle’s circumference to its diameter ≈ 3.14159. Fundamental in all geometry.
∴
Therefore
Logical conclusion symbol: ‘therefore’. Used in geometric proofs and logical derivations.
∵
Because
Indicates the reason or premise in a proof. Complement of ∴.
≅
Congruent to
Two geometric figures are congruent if they have the same shape and size.
∼
Similar to
Two figures are similar if they have the same shape but not necessarily the same size.
