'Trigonometry' comes from Greek: 'trigonon' = 'triangle' and 'metron' = 'measure'. So, basically, the measurement of triangles.

Archimedes
Hipparchus, who was a Greek astronomer
The word trigonometry originates from the two Greek words 'trigon' and 'metron'. While 'trigon' has the meaning of triangle, 'metron' means to measure. The literal translation of the word trigonometry is to measure triangles.
The Greek letter theta
"Trigonometry" comes from the Greek words trigonon and metron, and roughly translates to "the measurement of angles".

It was Pythagoras
Hipparchus is the father of trigonometry and he was a Greek astronomer who lived between 190-120 B.C. He is considered as the father of trigonometry, a branch of mathematics which studies the angles of sides of triangles. :)
well, nothing is for sure but it is said that Hipparchus, a Greek geographer. its kind of odd though. but they say that they have evidence of his systematic use of trigonometry. Also Menelaus and Ptolomy helped in the development of trigonometry.
From Greek: tri = threegon = corner metry = measurement.
