Trigonometry’s Rise

Dropping right triangles
in unexplored skies,
charting distances
from the center of the world,
constructing compass-generated lines…
“Let no one ignorant of Geometry
enter here,”
wrote Plato
at the academy’s entrance.
Similar triangles,
Pythagoras’ Theorem,
deriving the unknown
from the known,
distances given to measurements
that humans could never traverse.
The procession of logic,
the triumph of triangular skies,
the ratios and angles
of right triangles
so frequently used
their names emerged
from mystical minds
who ardently believed
that everything was number:
Sine
Cosine
Tangent,
Cosecant
Secant
Cotangent,
Arcsine
Arccosine
Arctangent,
right triangle ratios
filling up pages
in the academies of Earth
whose simplification of puzzles
precisely determined
the circumference of the Earth,
our distance to the Sun,
and other marvels
requiring no technology
simply rapt brains
astute eyes
and proficience
in trigonometry’s rise.
