This math topic focuses on proper labeling of sides in trigonometry problems. It practices identifying the "hypotenuse," the side opposite an angle (labeled as "opposite"), and the side adjacent to an angle (labeled as "adjacent"). Each question presents a different triangle and asks for the formal trigonometric name of a specific side, supported by a visual aid (an image of the triangle). These exercises are foundational for understanding trigonometry and its principles, such as the sine, cosine, and tangent functions, which relate the angles of a triangle to the lengths of its sides.
