10 cards from this deck
Any triangle (non-right-angled)
Two sides and the included angle
All three sides
a2=b2+c2−2bccosAa^2 = b^2 + c^2 - 2bc \cos Aa2=b2+c2−2bccosA
cosA=b2+c2−a22bc\cos A = \frac{b^2 + c^2 - a^2}{2bc}cosA=2bcb2+c2−a2
Opposite the longest side
Angle AAA is obtuse (between 90° and 180°)
Becomes Pythagoras' theorem (cos90°=0\cos 90° = 0cos90°=0)
Clockwise from North
Three-figure numbers (e.g., 037° not 37°)
