In collections UCSS Secondary Math II Unit 5 Lesson 8
This example demonstrates how to calculate the sine, cosine, and tangent ratios for angles A and B in triangle ABC. Key math concepts include the definitions of trigonometric functions, relationships between side lengths in a triangle, and the calculation of ratios. The construction uses GeoGebra commands like Polygon, Segment, and Angle, along with objects such as edges, masks, points, and distance measurements. It is suitable for high school students and teachers learning trigonometry and geometric constructions.

GeoGebra Commands & Parameters

  1. Polygon((Edge, y(Corner[1])), Corner[2], Corner[3], (Edge, y(Corner[4]))) → Mask, a, b, c, d
  2. Segment(C, B) → BC
  3. Segment(A, C) → AC
  4. Segment(A, B) → AB
  5. Angle(A, B, C) → ABC
  6. Angle(B, C, A) → BCA
  7. Angle(C, A, B) → CAB
  8. Segment(A, B) → AB2
