1
COS =
OPPOSITE ÷ HYPOTENUSE
OPPOSITE ÷ ADJACENT
HYPOTENUSE ÷ ADJACENT
ADJACENT ÷ HYPOTENUSE
2
Using the information in the image
only the distance along the ground can be calculated.
the plane is too high to measure its height
you need more information to calculate plane's height
the height of the plane can be calculated using trigonometry

The three main trigonometry functions are
sen , con , tan
soh , cah , toey
sin , cus , tam
sin , cos , tan
4
Beside the Hypotenuse , the 2 other sides of a right angled triangle are called:
adject and opponent
adjacent and opposite
Bennie and Joan
addant and oporto
5
SIN =
OPPOSITE ÷ ADJACENT
ADJACENT ÷ HYPOTENUSE
OPPOSITE ÷ HYPOTENUSE
HYPOTENUSE ÷ OPPOSITE
6
The hypotenuse of a right angled triangle is
the same as the letter "A" or "B" in the Pythagorean Theorem
opposite the right angle ("across" from the right angle)
the shortest side (the short leg)
the LONGEST side of the triangle

TAN =
OPPOSITE ÷ ADJACENT
OPPOSITE ÷ HYPOTENUSE
ADJACENT ÷ HYPOTENUSE
ADJACENT ÷ OPPOSITE
