we want to be able to quickly

distinguish and therefore we

use many different sets of letters

example : triangle

vertices are A, B, C

sides are a, b, c

angles are α, β, γ

{it}^{'} s easy to read, write and

understand things like :

c =∣ A B ∣

S = \frac{A + B + C}{3}

\frac{\sin α}{a} = \frac{\sin β}{b}

c^{2} = a^{2} + b^{2} - 2 a b \cos γ
