Law of Sines Quiz

What type of triangles can the Law of Sines be applied to?

• Right-angled triangles

• Non-right-angled triangles

• Equilateral triangles

• Isosceles triangles

If a triangle has a right angle, which methods might you use instead of the Law of Sines?

• Law of Cosines

• SOHCAHTOA

• Both Pythagoras' Theorem and SOHCAHTOA

• Pythagoras' Theorem

How is the Law of Sines formula written?

• cot A / a = cot B / b = cot C / c

• cos A / a = cos B / b = cos C / c

• sin A / a = sin B / b = sin C / c

• tan A / a = tan B / b = tan C / c

In a triangle, what do we call the side opposite angle A?

• Side B

• Side D

• Side C

• Side A

What is a 'matching set' in the context of the Law of Sines?

• An angle and its opposite side

• Two sides

• An angle and an adjacent side

• Two angles

How many matching sets do you need to use the Law of Sines effectively?

• One complete and one partial

• Two complete

• One partial

• Two partial

In the example problem, what is the unknown side labeled as?

• W

• Z

• Y

• X

What is the first step in solving for an unknown side using the Law of Sines?

• Add the known sides together

• Identify the matching sets

• Multiply both sides by the unknown

• Divide both sides by the known angle

If given two angles and one side, how can you find the third angle in a triangle?

• Use the Law of Cosines

• Subtract the sum of the given angles from 180°

• Multiply the given angles

• Divide the given angles by 2

What is the inverse operation of sine used for in the Law of Sines?
