Tangent Ratios and Triangle Properties

The video tutorial covers the tangent ratio in right-angled triangles, explaining how it relates an acute angle to the two shorter sides. It provides examples of calculating the tangent ratio and finding unknown sides using this ratio. The tutorial includes practical examples with different triangles and a real-world problem involving a flagpole.

What does the tangent ratio relate in a right-angled triangle?

• The hypotenuse to the opposite side

• An acute angle to the two shorter sides

• The adjacent side to the hypotenuse

• The opposite side to the hypotenuse

What is the tangent ratio used for in trigonometry?

• To calculate the area of a triangle

• To relate an angle to two sides

• To determine the perimeter

• To find the hypotenuse

Which formula represents the tangent of an angle theta?

• tan(theta) = adjacent / hypotenuse

• tan(theta) = adjacent / opposite

• tan(theta) = hypotenuse / opposite

• tan(theta) = opposite / adjacent

Which side is opposite the right angle in a triangle?

• Adjacent side

• Opposite side

• Hypotenuse

• None of these

In the formula tan(theta) = opposite/adjacent, what does 'adjacent' refer to?

• The longest side

• The side next to the angle

• The shortest side

• The side opposite the angle

What is the first step in solving for a missing side using the tangent ratio?

• Calculate the angle

• Find the perimeter

• Identify the opposite and adjacent sides

• Identify the hypotenuse

In a triangle with sides 3, 4, and 5, which side is the hypotenuse?

• None of these

• 5

• 4

• 3

For a triangle with sides 3, 4, and 5, what is tan(theta)?

• 3/5

• 4/3

• 4/5

• 3/4

In Example A, what is the value of tan(theta) for the triangle with sides 3, 4, and 5?

• 0.75

• 0.5

• 0.6

• 0.8

In a triangle with sides x, y, and z, which side is the hypotenuse?

• x

• y

• z

• None of these
