12 cards from this deck
Any triangle (not just right-angled)
sinAa=sinBb=sinCc\frac{\sin A}{a} = \frac{\sin B}{b} = \frac{\sin C}{c}asinA=bsinB=csinC
asinA=bsinB=csinC\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}sinAa=sinBb=sinCc
To find unknown angles
To find unknown side lengths
Lowercase letters for sides, uppercase for vertices
Two angles + one side or two sides + opposite angle
Two possible angle solutions when using sine rule to find angle
180°−first angle180° - \text{first angle}180°−first angle
Only round final answer, not intermediate steps
Check angles sum to 180°180°180°
