Slide 2:
The first special triangle you should become familiar with is
the 45 – 45 – 90 triangle. Remember from
Geometry… 1 1 45 45 Sin 45 =
Cos 45 =
Tan 45 = opposite adjacent hypotenuse
Slide 3:
Now onto the 30 – 60 – 90 triangle. 30 60 1 2 For 30 degrees… opposite adjacent hypotenuse Sin 30 =
Cos 30 =
Tan 30 = For 60 degrees… Sin 60 =
Cos 60 =
Tan 60 = opposite adjacent
