SOH CAH TOA

Front

What does SOH CAH TOA stand for?

Back

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

How do you find the sine of an angle in a right triangle?

Back

To find the sine of an angle, use the formula: sin(θ) = Opposite side / Hypotenuse.

Front

How do you find the cosine of an angle in a right triangle?

Back

To find the cosine of an angle, use the formula: cos(θ) = Adjacent side / Hypotenuse.

Front

How do you find the tangent of an angle in a right triangle?

Back

To find the tangent of an angle, use the formula: tan(θ) = Opposite side / Adjacent side.

Front

If the opposite side is 32 and the hypotenuse is 40, what is sinA?

Back

sinA = 32/40.

Front

If the adjacent side is 16 and the hypotenuse is 34, what is cosC?

Back

cosC = 16/34.

Front

What is the relationship between the angles in a right triangle?

Back

The sum of the angles in a right triangle is always 180 degrees, with one angle being 90 degrees.

Front

How can you find a missing angle in a right triangle?

Back

You can find a missing angle using the sine, cosine, or tangent ratios, or by using the fact that the sum of the angles in a triangle is 180 degrees.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b): c² = a² + b².

Front

If you know two sides of a right triangle, how can you find the third side?

Back

You can use the Pythagorean theorem: c² = a² + b², where c is the hypotenuse and a and b are the other two sides.
