- 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!
