meoraeOk. So on Friday, in math we had a test. There were seven questions on the test. The first question was to prove that if any two medians in a triangle are congruent, then the triangle is isosceles. I spent half of the period trying to figure that out before moving on. Then I came back during my directed study to finish the other question I didn't get to and I spent that whole period staring at the first question again. Elisabeth, Emily and Katy also couldn't figure out how to prove it. During lunch, which was after math, I showed it to my brother, Giulia and Josh, all who I thought were very good at math, and none of them could get it. During the directed study, I finally gave up and asked Mr. Kraus if it was possible to prove it and he spent five minutes looking at it and getting nowhere. He called in another math teacher and asked him if he knew how to prove it and he couldn't either. So the 8 people I know that are good at math, besides myself, couldn't prove this problem. I showed it to my dad when I got home, he couldn't prove it. Elisabeth asked her dad how to prove it and he couldn't. Then on Saturday, as Emily's dad was driving Emily, Hannah, and me to fencing, Emily and I were talking about it. Hannah couldn't think of how to prove it either. So that's 12 people, including myself, who didn't know how to prove it. Emily's dad goes home, spends like 15 minutes working on it and proved what the 12 of us couldn't prove. The proof is 21 steps long, has nothing to do with what we are currently learning, and involves knowing how to use the properties of similar triangles in a proof. This year we haven't even gone over what similar triangles are, much less how to use them. Mr. Kraus isn't counting that question on the test as he, himself, didn't know how to solve it.
I spent most of today going outside for half-an-hour to forty-five minutes and shoveling the two feet of snow that fell last night. I'd get cold, come back in, warm up and relax for the next hour. Then I'd start over again. A huge snow drift is in our driveway. There's places where the snow's five feet tall and other places where it's only an inch. The back door can't be opened because there's too much snow in front of it. I get to dig out the back door tomorrow, but at least I don't have to get up early.
