Trigonometric functions
... Trigonometry is most simply associated with planar right-angle triangles (each of which is a two-dimensional triangle with one angle equal to 90 degrees). The applicability to non-right-angle triangles exists, but, since any non-right-angle triangle (on a flat plane) can be bisected to create two ri ...

... A line that intersects two (or more) parallel lines is called a transversal. The transversal and the parallel lines form a total of eight angles. There are many pairs of congruent angles and many pairs of supplementary angles. ...

... so it suffices to show that A lies on the pole of H. Let D and E be the feet of the altitudes from A and B, respectively; these also lie on the circle, and H = AD ∩ BE. The polar of the line AD is the intersection of the tangents AA and DD, and the polar of the line BE is the intersection of the tan ...
