Something that I have learned this year in math is how to figure out the length of a slanted line by turning it into a triangle. If there are two points and you need to find the distance between them, you can could count how many it rises (A) and then how many it runs to one side (B). then you make A and B to the second power (²). A² plus B², equals C². So first you have to figure out what A and B are to the second power, than you can add the them. Now, you have a certain number that equals C². In order to get it out of the second power (²), you have to find the square root of that number. Than that is your answer.
You can use this in real life for many things. It is helpful to find the diagonal of any square or triangle. If you are trying to find the across length of a TV or some other kind of electronic (Laptop screen, Phone screen, etc.) When buying any of these items you may want to know the diagonal length. Another example would be if you are getting a picture frame, poster, etc, you might need to know it so that you know for sure if it will fit in the spot on the wall you want it to. It is just a really great thing to know, that I will probably use frequently in real life.
