HON - Trig Test

Front

What is the formula for the area of a sector?

Back

Area = (θ/360) * π * r², where θ is the angle in degrees and r is the radius.

Front

How do you use the Law of Sines?

Back

The Law of Sines states that (a/sinA) = (b/sinB) = (c/sinC), where a, b, and c are the lengths of the sides of a triangle and A, B, and C are the angles opposite those sides.

Front

What is the Law of Cosines?

Back

The Law of Cosines states that c² = a² + b² - 2ab*cosC, where c is the side opposite angle C.

Front

How do you calculate the area of a triangle using the Law of Sines?

Back

Area = (1/2) * a * b * sinC, where a and b are two sides of the triangle and C is the included angle.

Front

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

Back

In a right triangle, the sine, cosine, and tangent functions relate the angles to the ratios of the sides.

Front

How do you find the length of a side in a triangle using the Law of Cosines?

Back

Rearrange the formula: c = √(a² + b² - 2ab*cosC) to solve for the unknown side.

Front

What is the formula for the area of a triangle given two sides and the included angle?

Back

Area = (1/2) * a * b * sinC.

Front

How do you convert degrees to radians?

Back

Radians = Degrees * (π/180).

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2 * π * r, where r is the radius.

Front

What is the relationship between the radius and the area of a circle?

Back

Area = π * r², where r is the radius.
