Question

please someone help me:( seriously no one wants to help...

Complete a two column proof for this problem.

Given: side AB= side AD and CA= side EA
Prove: triangle ABC= triangle ADE

Answer 1

well the angles between the given sides have to be equal

Angle CAB = angle DAE Vertically opposite angles...

so your proof is by SAS postulate

Answer 2

where is the two column:)

Answer 3

@campbell_st is that the 2 column proof?

Answer 4

well in Australia our 2 column proofs are slightly different to the US

but this is what I'd write for my classes..



hope this helps...
