Which pattern doesn’t belong?[br][br][img width=478,height=429]https://lh6.googleusercontent.com/TJPoy_VEfgIDOjraAttIiIKekHOs-fkMtALry-FvWgu5gLvRoDoxVSsnuKgn-jlT_cVQUlCklwkCcjw_LguRdqwHRhV5jqL5m5Mlj4HCjd3NOfupq06IGL1TbhlISfPEFiEiKn50[/img][br][br] Explain why you think this pattern choice doesn't belong here.
[size=150]In your pattern, which shapes cover more of the plane: [i]blue rhombuses[/i], [i]red trapezoids[/i], or [i]green triangles[/i]?  Explain how you know.[/size][br][br]You may use the sliders and the shapes in this app to help. Explore what you can see or hide, and what you can move or turn. [br][br]Select the statement that best applies. (If your teacher assigned both patterns to you, select 2 answer choices.)
Your teacher will assign you to look at Pattern A or Pattern B.
For the previous question, identify the pattern you were assigned and explain how you know your answer to the previous question is true.
