（2） 当不是已知边所夹时 (i) 若已知角大于等于90度，三角形唯一，(ii) 若已知角为锐角时三角形不唯一（有两种情况）。两条边和一个角不能确定一个三角形，比如有边边角、边角边两种情况。

To calculate the area of a triangle given one side and two angles, solve for another side using the Law of Sines, then find the area with the formula: area = 1/2 × _b_ × _c_ × sin(A). Find Third Angle
Five easy to use calculators to solve right triangle problems depending on which information you are given. The figure shown below will be used for sides and angle notations. In the above right triangle the sides that make and angle of 90° are a and b, and h is the hypotenuse. ...
Triangle Angle Calculator The Triangle Angle Calculator is a tool that calculates the angles of a triangle given the length of its sides. To use the calculator, the user simply inputs the length of the three sides of the triangle and the calculator will use the law of cosines to determine ...
2ab cosC) if you are given 3 sides and 0 angles, or if you are given two sides and the angle opposite the missing side. The Law of Sines (a/sinA = b/sinB = c/sinC) can be used any time you know the length of one side and its opposite angle and one other side or angle. ...
An interior angle of a triangle is formed by two sides of the triangle. An exterior angle is formed by one side of the triangle and the extension of an adjacent side. Each exterior angle has two remote interior angles. A remote interior angle is an interior angle that is not adjacent to...
A triangle’s sides may be referred to by their end points (such as AB), and their lengths may be represented by the lowercase letter of the opposite angle (for example, c being the length of AB). In the case of right triangles, the side lengths are given specific names: the ...
