Unit 3, Day 8: Objective: Triangle inequalities.
Define: Triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side.
To know if given lengths can be a triangle, you add two sides together that are not the hypotenuse; they should be greater then the length of the hypotenuse. To find the range of possibilities of the length of the third side, you add together to two given lengths and that is what "x" can be less then, and you subtract the two points and that is what "x" can be greater than. The inequality should have the lowest number, then a greater than sign, then the x, followed by a less than sign and the highest number. See problems 1 and 4 for examples.
