Storyboard Text

  • Hey Sarí! Are you headed to math class? I'll walk with you.
  • Yeah me too.
  • Thanks Alex, I hope we do something fun in math today.
  • Good morning students! Today I would like you solve this problem on the board, then pair up and share your reasoning with a partner.
  • Today we will be using standard 3, check the chalkboard to for the problem and the standard.
  • Show that two triangles are similar using the 3 triangle theorems.
  • PS.3 Construct Viable Arguments and Critique the reasoning of others.
  • Hmm. I remember triangle theorem SSS from yesterday. I'll use that one to solve the problem.
  • The easiest way to do this would be to compare the angles in the AA theorem.
  • Show that two triangles are similar using the 3 triangle theorems.
  • PS.3 Construct Viable Arguments and Critique the reasoning of others.
  • I used theorem SSS to prove that the triangles are similar.
  • I made and compared the ratios of the sides of the triangles.
  • PS.3 Construct Viable Arguments and Critique the reasoning of others.
  • Show that two triangles are similar using the 3 triangle theorems.
  • If the angles are the same then it doesn't matter the lengths of the sides.
  • PS.3 Construct Viable Arguments and Critique the reasoning of others.
  • Show that two triangles are similar using the 3 triangle theorems.
  • I don't agree. I used the AA theorem to prove the triangles are similar.
  • Surprise! You both are right! There is more than one way to solve this proof.
  • NO WAY!
  • PS.3 Construct Viable Arguments and Critique the reasoning of others.
  • Show that two triangles are similar using the 3 triangle theorems.
