Review how to evaluate trig functions when given a triangle

The video tutorial explains the properties of triangles, focusing on right triangles and the role of angle Theta. It covers the identification of triangle sides: hypotenuse, adjacent, and opposite. The tutorial then demonstrates how to calculate trigonometric ratios such as sine, cosine, and tangent using these sides. It also discusses the reciprocal identities of these trigonometric functions, including cosecant, secant, and cotangent.
