Are these triangles congruent?

• Yes, by ASA

• Yes, by SAS

• Yes, by AAS

• No, this is the SSA one!! (We don't say bad words in Geometry)

When can you use CPCTC?

• Before triangles are congruent

• Whenever you wants, there are no restrictions

• After triangles are congruent

• There is no such thing as CPCTC
