Trig Ratios

Front

What is the ratio of Tangent W?

Back

Tangent W = \frac{\text{Opposite}}{\text{Adjacent}} = \frac{12}{9} = \frac{4}{3}

Front

What is tan(A)?

Back

tan(A) = \frac{\text{Opposite}}{\text{Adjacent}} = \frac{a}{b}

Front

What is the adjacent leg to angle A?

Back

The adjacent leg to angle A is b.

Front

From ∠C, the 36 would be considered what?

Back

The 36 would be considered the Adjacent Side.

Front

What is cos(A)?

Back

cos(A) = \frac{\text{Adjacent}}{\text{Hypotenuse}} = \frac{b}{c}

Front

What is the definition of SOH-CAH-TOA?

Back

SOH-CAH-TOA is a mnemonic for remembering the definitions of sine, cosine, and tangent: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.

Front

What is the sine of angle A?

Back

sin(A) = \frac{\text{Opposite}}{\text{Hypotenuse}} = \frac{a}{c}

Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

If the opposite side is 15 and the adjacent side is 20, what is tan(A)?

Back

tan(A) = \frac{15}{20} = \frac{3}{4}.

Front

What is the relationship between sine and cosine?

Back

sin(A) = cos(90° - A) and cos(A) = sin(90° - A).
