TRIGONOMETRY:
The right Triangle- right triangle is a triangle with one angle measures 900.
- a geometrical figure with three sides with two rays measures 900 for an angle.
- a triangle that contains ninety degree angle and no equal sides except for the isosceles right triangle whose two legs are equal.
Illustration:
The six Trigonometric functions of
angle A
Sine A = opposite/ hypotenuse = o / h
Cosine A = adjacent/ hypotenuse = a / h
Tangent A = opposite/adjacent = o / a
Cotangent A = adjacent/ opposite = a / o
Secant A = hypotenuse/ adjacent = h / a
Cosecant A = hypotenuse/
opposite = h / o
