How to write the three trigonometric ratios for a triangle

The video tutorial explains how to find the ratios of sine, cosine, and tangent for a given angle in a triangle. It covers labeling the hypotenuse, adjacent, and opposite sides, and introduces the concept of using Theta and Sokola to remember these trigonometric ratios. The tutorial also includes practical examples of calculating these ratios for specific angles.

Which side of a right triangle is always opposite the right angle?

• Base

• Adjacent side

• Hypotenuse

• Opposite side

In a right triangle, what is the side called that is between the angle of interest and the 90-degree angle?

• Base

• Adjacent side

• Hypotenuse

• Opposite side

What does the mnemonic 'SOHCAHTOA' help you remember?

• The Pythagorean theorem

• The order of operations

• The types of triangles

• The ratios for sine, cosine, and tangent

If the opposite side is 4 and the hypotenuse is 5, what is the sine of the angle?

• 3/4

• 5/4

• 4/5

• 3/5

What is the tangent of an angle if the opposite side is 4 and the adjacent side is 3?

• 5/3

• 3/5

• 3/4

• 4/3
