Tangent Function in Trigonometry - Definition and Right Triangle Visualization #3699744 (License: Personal Use)

This diagram illustrates the definition of the tangent function in trigonometry using a right-angled triangle. The angle θ is at the base, with the side opposite to it labeled “opposite,” the side next to it (but not the hypotenuse) labeled “adjacent,” and the right angle clearly marked. The formula tan θ = opposite / adjacent is displayed below the triangle to reinforce the relationship.

Used in educational content for high school or college math courses covering trigonometry; ideal for lessons on SOHCAHTOA, unit circle foundations, or solving right-triangle problems. Matches user intent for visual learners seeking conceptual clarity.
