SOH-CAH-TOA TEST

Front

What does SOH-CAH-TOA stand for?

Back

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

Front

In a right triangle, which side is the hypotenuse?

Back

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

Front

How do you identify the opposite side in a right triangle?

Back

The opposite side is the side that is across from the angle you are considering.

Front

What is the sine function used for in trigonometry?

Back

The sine function is used to find the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine function used for in trigonometry?

Back

The cosine function is used to find the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent function used for in trigonometry?

Back

The tangent function is used to find the ratio of the length of the opposite side to the length of the adjacent side.

Front

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

Back

You can use the Pythagorean theorem: a² + b² = c², where c is the hypotenuse.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

How do you find the measure of an angle in a right triangle using trigonometric functions?

Back

You can use the inverse trigonometric functions: sin⁻¹, cos⁻¹, or tan⁻¹, depending on the sides you know.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the angles in any triangle is always 180 degrees.
