Trig Ratios: Missing Side Lengths

Front

What is the definition of Trigonometric Ratios?

Back

Trigonometric ratios are relationships between the angles and sides of a right triangle, specifically sine, cosine, and tangent.

Front

What is the formula for sine (sin) in a right triangle?

Back

sin(θ) = Opposite side / Hypotenuse

Front

What is the formula for cosine (cos) in a right triangle?

Back

cos(θ) = Adjacent side / Hypotenuse

Front

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

Back

tan(θ) = Opposite side / Adjacent side
