 This video is called Practice Problems 2. This problem is really quite simple if you know what you need to do. It says, if two sides of a triangle are 6 and 14, so that means the lengths of them are 6 and 14 units long, then the third side must be bigger or greater than blank, but less than blank. So this is actually a range problem. And we learned in previous videos to find the range of what the third side could be. You simply take the two sides you're given and add them together. So 6 plus 14 equals 20. And then you take the two sides and subtract them. And always subtract them in a way that gives you a positive answer. So do your bigger number minus your smaller number. So to fill in the blanks here, the third side must be bigger than 8, but less than 20. If you have something below 8 or more than 20, it won't make a triangle. The three sides will not be able to meet up correctly to make a triangle shape.
