How do we determine the three trig ratios for a triangle

The video tutorial explains how to determine the sides of a triangle, focusing on the trigonometric functions sine, cosine, and tangent. It highlights the importance of correctly identifying the hypotenuse, adjacent, and opposite sides when calculating these functions. The tutorial provides step-by-step guidance on calculating the trigonometric ratios for a given angle, ensuring a clear understanding of the concepts involved.

What is the main challenge when identifying the sides of a triangle for trigonometric calculations?

• Finding the hypotenuse

• Determining which side is adjacent and which is opposite

• Identifying the right angle

• Calculating the area of the triangle

Which side is always opposite the 90-degree angle in a right triangle?

• Adjacent side

• Opposite side

• Hypotenuse

• Base

When calculating the sine of angle S, which sides are involved?

• Opposite over hypotenuse

• Adjacent over opposite

• Hypotenuse over opposite

• Adjacent over hypotenuse

How is the cosine of angle S calculated?
