Question 890857
AM = BI due to the two given statements. AI is common to both triangles IMA and ABI, so by SAS, the two triangles are congruent. You can fill out the rest of the details but there isn't much.


PS: I have never constructed a flowchart proof, and I haven't used a two-column proof since I took geometry in middle school (I'm a mathematics major!). I have a feeling that you're supposed to combine the three statements together to get your conclusion, but honestly it is much easier to understand with a paragraph or two-column proof.
