#### 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!﻿
