Integrated Math II · Week 23 · Similarity and Right Triangle Trigonometry
Similar, Not the Same
Dilations make similar figures; similar experiences are not identical ones.
- Students will
- Students dilate a triangle from the origin by a scale factor of 2 and show that side lengths scale while angles stay the same.
- SEL skill
- Describe how a similar experience can differ from your own
- What it looks like
- Students take others' perspectives by noticing that similar experiences are not identical ones.
- Content focus
- Dilations and similar figures
- Format
- Partner exchange
