Integrated Math II · Week 26 · Similarity and Right Triangle Trigonometry
Right Triangle Ratios
Discovering sine, cosine, and tangent through measurement patterns.
- Students will
- Students find sine, cosine, and tangent ratios in right triangles and see that sine of an angle equals cosine of its complement.
- SEL skill
- Notice what keeps you going when a pattern is hard to see
- What it looks like
- Students persevere through a pattern that is hard to see at first and notice what keeps them going.
- Content focus
- Sine, cosine, and tangent ratios
- Format
- Think write pair share
