An Area Formula for Triangles
... lesson, the formula only applied to acute triangles because the trigonometry functions were only defined for acute angles. This lesson begins by introducing the area formula and then making a connection to the definition of the sine function presented in Algebra II Module 2. In the Exploratory Chall ...

Special Segments in Triangles
... » An angle bisector is a line, ray, or segment that divides an angle into two congruent smaller angles. ANGLE BISECTOR THEOREM If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle. If AD bisects BAC and DB = AB and DC = AC, then DB = DC ...

... 8. Hyperbolic triangles Note: This year, I’m not doing this material, apart from Pythagoras’ theorem, in the lectures (and, as such, the remainder isn’t examinable). I’ve left the material as Lecture 8 so that (i) anybody interested can read about hyperbolic trigonometry, and (ii) to save me having ...
