Plane Geometry - UVa-Wise
... The opening lines in the subject of geometry were written around 300 B.C. by the Greek mathematician Euclid in 13 short books gathered into a collection called The Elements. Now certainly geometry existed before Euclid, often in a quite sophisticated form. It arose from such practical concerns as pa ...

Trigonometry
... The angles whose terminal sides fall in quadrants II, III, and IV will have values of sine, cosine and other trig functions which are identical (except for sign) to the values of angles in quadrant I. The acute angle which produces the same values is called the reference angle. ...

... introduced as “half the chord of twice the arc” (Q 46) without any further explanation. This was probably not very helpful for a beginning student of geometry who had never worked with chords and sines before. At some point, someone made an edited version of the text, which has been preserved in one ...
