Example
∠ angle formed by two rays ∠ABC = 30º
∟ right angle = 90º α = 90º
spherical angle AOB = 30º
´ arcminute 1º = 60´ α = 60º59′
º degree 1 turn = 360º α = 60º
´´ arcsecond 1´ = 60´´ α = 60º59’59”
[latex]\overrightarrow{AB}[/latex]< ray line that start from point A
AB line segment the line from point A to point B
| perpendicular perpendicular lines (90º angle) AC | BC
≅ congruent to equivalence of geometric shapes and size ∆ABC ≅∆XYZ
|| parallel parallel lines AB || CD
Δ triangle triangle shape ΔABC ≅ΔBCD
~ similarity same shapes, not the same size ∆ABC ~∆XYZ
π pi constant π = 3.141592654…
is the ratio between the circumference and diameter of a circle
c = π·d = 2·π·r
|x–y| distance distance between points x and y | x–y | = 5
grad grads grads angle unit 360º = 400 grad
rad radians radians angle unit 360º = 2π rad
The symbols for angles and triangles are most important and frequently used symbols in geometry
