• Yes, 841 equals 841

• No, 841 does NOT equal 841
  

Based on the information in the model, which equation represents the Pythagorean Theorem? (Find the  $\sqrt{ }$  of each value, then put them into  $a^2\ +\ b^2\ =\ c^2$  )

• 
  

  $6^2\ +\ 8^2\ =\ 10^2$
  

• $36^2\ +\ 64^2\ =\ 100^2$

• $6\ +\ 8\ =\ 10$

• $10^2\ +\ 6^2\ =\ 8^2$

Based on the information in the model, which equation represents the Pythagorean Theorem? (Find the  $\sqrt{ }$  of each value, then put them into  $a^2\ +\ b^2\ =\ c^2$  )

• $9^2\ +\ 12^2\ =\ 15^2$

• $81^2\ +\ 144^2\ =\ 225^2$

• $9\ +\ 12\ =\ 15$

• $15^2\ +\ 9^2\ =\ 12^2$
