Pythagorean Theorem


After a week of being away from home, I’m finally back in school.  My favorite thing that we learned about today was the Pythagorean Theorem.

We went to the chalkboard table and started talking (and writing) about shapes and their angles.  When we got to the right triangle, we started talking about how to find the distance of the longest side (the hypotenuse)using the Pythagorean Theorem.  You have to know a little bit about exponents to find it.

A few things you should know are that the longest side on a right triangle is called a hypotenuse and the shorter sides are called the legs.  Let’s say that the legs are a and b, and that they both measure 4 in.  You would write down c2 = a2 +b2.   We already know that both a and b equal 4, so all you need to do is add 42 and 42.  That would equal 32 in.  Now we know that 32 in. = c2.  All we need to do now is figure out what the square root of 32 is.  The answer is 5.7.  After that much work, you now know that the length of the hypotenuse is 5.7 in.  Wasn’t that easy? 😉

Oh, and by the way, it makes a lot more sense on paper. 😉
