Interior angles of a triangle must equal 180 degrees.
Exterior angles of a triangle equal 360 degrees.
For example, a right triangle with two equal sides has one angle of 90 degrees and 2 angles both 45 degrees = 180 degrees.
Another example: 30-60-90 triangle = 180 degrees
I guess that, being from overseas, that one learns more about other countries then one does about ones own. Then again I only know about two huge rivers in the US. Guess I lucked out.
You don’t remember, because you don’t use it anymore. At some point I’m sure you knew most of the questions… But when you aren’t trying to remember something after 15+ years you are going to forget it.
I’m guessing they also pick the smartest kids in 5th grade so these kids have all this stuff down since its within a year or so of when they learned it
I remember one and I think they asked which was larger, the moon or the sun. You can guess the answer they gave. Granted though, when you are on TV with the lights and action I can believe it would distract many folks.
“According to Wikipedia, it is the Yukon. I would have never guessed that.”
Apparently, Wikipedia is not smarter than a 5th grader. The answer is the Missouri River, which is longer than the Mississippi. The Yukon is 1980 miles long.
Yup, I would have said Missouri too, but Wiki says that doesn’t count as it is a tributary of the Mississippi. According to them the longest in the U.S. is the Jefferson-Missouri-Mississippi, the second longest is the Yukon.
But you are right is that they have the wrong length for the Yukon on their “longest rivers of the world page”
