Trigonometric Functions and Properties

The video tutorial introduces trigonometry, focusing on labeling triangle sides and understanding trigonometric functions like sine, cosine, and tangent. It explains how to apply these functions to solve problems and demonstrates using a calculator to find solutions, emphasizing the importance of ensuring the calculator is in degree mode.

What should you do first when given an angle in a triangle?

• Determine the perimeter

• Find the area of the triangle

• Label the adjacent and opposite sides

• Calculate the hypotenuse

What is the purpose of labeling sides in a triangle?

• To determine the type of triangle

• To find the perimeter

• To avoid confusion later

• To calculate the area

Which side is the hypotenuse in a right triangle?

• The side opposite the given angle

• The side adjacent to the given angle

• The side opposite the right angle
