2. 2.1.2 Flowcharts for Congruence (Two column proofs)
Using flowcharts, paragraph proofs or two column proofs how can you support why triangles are congruent I do more 2 column proofs, I think they are easier but I will show you other methods and then you get to choose which makes the most sense for you, all of them have the same basic concepts Try to do investigations 2.12 and 2.13

3. 2 Column Proof Statement – usually what is congruent, or measurements
Reason – why you can write the statement
State what is given in the problem, either already marked in the picture or they tell you
State other parts of triangles congruent and give a reason why
Vertical angles
Definitions such as midpoint or bisect
Reflexive property – side shared in 2 triangles, could be a common angle
Symmetric property a=b and b=a
Transitive property a=b, b=c therefore a=c
State triangles congruent, congruency statement and why congruent
