... What you need to know Right-angled triangles are a unique form of triangle. In general, most triangles are oblique triangles. That is, the three angles are all different and not one of them is a right angle. The methods for calculating oblique triangles are much more complex than for right-angled tr ...

The Law of Sines
... What this says is that you can set up the ratio of the sine of any angle in a triangle and the side opposite it and it will equal the ratio of the sine of any other angle and the side opposite it. If you know three of these pieces of information, you can then solve for the fourth. ...

MATH 131 Problem Set 5
... This problem set deals with the concurrence theorems for triangles. These theorems have a common format: given triangle ABC, then three lines, one associated with each vertex or with each side, are concurrent at a point, that is, all three of them pass through a certain point. Note: (November 20) In ...

... we find that the cosine of the vertex angle at V (hence also at U and W) is equal to 1/3, so that the degree angular measurement of the vertex angles in the spherical triangle are equal to approximately 70.528779 degrees because the latter angle is approximately equal to the inverse cosine of 1/3. C ...
