Trig Intro

Front

What is the ratio of cosine (cos) in a right triangle?

Back

Adjacent side / Hypotenuse

Front

What does the acronym SOHCAHTOA stand for?

Back

SOH: Sine = Opposite / Hypotenuse, CAH: Cosine = Adjacent / Hypotenuse, TOA: Tangent = Opposite / Adjacent

Front

What is the ratio for tangent (tan) in a right triangle?

Back

Opposite side / Adjacent side

Front

What does theta (θ) represent in trigonometry?

Back

An unknown angle in a triangle

Front

In a right triangle, what is the opposite side?

Back

The side opposite to the angle of interest (θ)

Front

What is the hypotenuse in a right triangle?

Back

The longest side of the triangle, opposite the right angle

Front

What is the adjacent side in a right triangle?

Back

The side next to the angle of interest (θ) that is not the hypotenuse

Front

How do you calculate sine (sin) of an angle?

Back

Sine = Opposite side / Hypotenuse

Front

How do you calculate cosine (cos) of an angle?

Back

Cosine = Adjacent side / Hypotenuse

Front

How do you calculate tangent (tan) of an angle?

Back

Tangent = Opposite side / Adjacent side
