Opp/Hyp

Front

Define the term 'hypotenuse' in a right triangle.

Back

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

Front

What does 'Opp' stand for in trigonometric ratios?

Back

Opposite side to the angle in question.

Front

What does 'Adj' stand for in trigonometric ratios?

Back

Adjacent side to the angle in question.

Front

What is the relationship between sine, cosine, and tangent?

Back

Tangent is the ratio of sine to cosine: tan(X) = sin(X)/cos(X).

Front

How can you find the length of a side using trigonometric ratios?

Back

Use the appropriate ratio (sin, cos, or tan) based on the known sides and the angle.
