Trigonometric Ratios Demo by Mr. Brash
Loading the math board and drawing, please wait…
This example demonstrates the relationships between side lengths and angles in a right triangle, focusing on trigonometric functions (sine, cosine, tangent). It involves core concepts like right triangles, trigonometric ratios, and the relationships between sides and angles. The construction uses GeoGebra commands such as Intersect, Segment, and Angle, with objects like r (radius), C (center), B (right angle vertex), A (acute angle vertex), Opp (opposite side), Adj (adjacent side), Hyp (hypotenuse), α (acute angle), β (acute angle), and γ (right angle). Suitable for high school students learning trigonometric definitions and properties.
