10 cards from this deck
Break into simpler 2D problems with right-angled triangles
Pythagoras' Theorem, Sin, Cos, Tan
Spotting where the right-angled triangles are in 3D shape
Draw it out flat to reduce to 2D
Hypotenuse (HHH), Opposite (OOO), Adjacent (AAA)
Pythagoras' Theorem
Sin, Cos, Tan ratios
a2+b2=c2a^2 + b^2 = c^2a2+b2=c2 where ccc is hypotenuse
tan(θ)=OppositeAdjacent\tan(\theta) = \frac{\text{Opposite}}{\text{Adjacent}}tan(θ)=AdjacentOpposite
Project the relevant triangle onto a flat plane
