Question

A student made the following chart to prove that AB2 + BC2 = AC2:
I will post the image after

Statement: BC2 = AC • DC
2)Justification: BC ÷ DC = AC ÷ BC because triangle ABC is similar to triangle BDC

4) Statement: AB2 = AC • AD
4)Justification: AB ÷ AD = AB ÷ AC because triangle ABC is similar to triangle ABD

1)Statement:Triangle ABC is similar to triangle BDC
1)Justification:Angle ABC = Angle BDC and Angle BCA = Angle BCD

3)Statement:Triangle ABC is similar to triangle ABD
3)Justification: Angle ABC = Angle ADB and Angle BAC = Angle BAD
