Well a interior angle is a curve type thing where two lines cross it will look like half a oval or circle. Your Using the letters to create this half and oval shape and to help us understand a Interior angle we know J,I, and L are connected so we can look at and connect those letting us know what the other one should look like. Connecting each option (KLN, JIG, KIL and HIG) Will let us know if they match JIL or not. KLN is smaller then JIL making it incorrect and that also tells us that JIG is incorrect since it matches KLN but compare it anyways. Now we check KLI doing that shows us that it does match JIL and it may be the answer but let's compare HIG to JIL anyways By doing this we see that HIG is a lot bigger and that it does not match JIL leaving us with choice C.
I hope this helped I had no idea what a Interior angel was so i looked up what it was then self taught from there im sure there is more to it, But I hoped this helped you have a great day!!! :)
