What are the trigonometric definitions of a right triangle

The video tutorial explains the basics of right triangles and trigonometric functions. It begins with an introduction to right triangles and the Pythagorean theorem, emphasizing the importance of the hypotenuse. The instructor then differentiates between the adjacent and opposite sides of a triangle when an angle is chosen. The tutorial covers the six trigonometric functions: sine, cosine, tangent, and their reciprocals, cosecant, secant, and cotangent. The video concludes with a summary and an invitation for viewers to ask questions.

What is the hypotenuse in a right triangle?

• The side adjacent to the right angle

• The side opposite the smallest angle

• The side adjacent to the largest angle

• The side opposite the right angle

Which side is considered the adjacent side in a right triangle?

• The side between the chosen angle and the right angle

• The side opposite the chosen angle

• The longest side of the triangle

• The side opposite the right angle

What is the sine of an angle in a right triangle?

• Hypotenuse over opposite side

• Opposite side over adjacent side

• Opposite side over hypotenuse

• Adjacent side over hypotenuse

What is the reciprocal of the sine function?

• Secant

• Tangent

• Cosecant

• Cotangent

Which trigonometric function is the reciprocal of cosine?

• Cotangent

• Secant
