  1. GBK Geometry Jordan Johnson

  2. Today’s plan • Greeting • Unit 4 Test Statistics • Lab • Homework / Questions • Clean-up

  3. Unit 4 Test Statistics

  4. Lab • Topics to investigate in GeoGebra: • How do you “undo” each of the transformations? • Composite transformations: • What happens when you rotate and rotate again? • Around the same point? • Around different points? • Or translate and translate again? • Or translate and rotate? • Or reflect and reflect again? • Is any of those composite transformations the same as one single transformation? • Look for opportunities to make conjectures • Do constructions (from the log)

  5. Lab • Topics to investigate in GeoGebra: • Composite transformations:Is there a single transformation equivalent to… • …translating twice, with different slopes & distances? • …reflecting twice across different lines? • Look for opportunities to make conjectures • Do constructions (from the log)

  6. Homework • For tomorrow: • 20 min Khan Academy • Look for recommendations • None? Pick a topic or do Mastery Challenges. • Think about the problems, write down any new observations or questions. • Rope • Circle center • Obtuse  Acute Triangle Dissection

  7. Clean-up / Reminders • Pick up all trash / items. • Push in chairs (at front and back tables). • See you tomorrow!
