This math topic focuses on the basics of trigonometry, particularly on labeling side ratios of right triangles. The problems ask students to identify the correct trigonometric function (sine, cosine, or tangent) for given side ratios such as opposite/hypotenuse, opposite/adjacent, and adjacent/hypotenuse. The format encourages recognizing these fundamental relationships within trigonometry, which are essential for understanding more advanced concepts in the subject.
