Calculate the perimeter of the triangle formed by the middle points of the sides of the triangle formed by points A(-8,6) B (2,5) and C (1,7) I've already got the distance between all the points given but I do not know what to do next. Can you help me?

**Urgent! Pre-Cal**

Well, if the triangle formed is of type rectancgle, then what you need to use is Pythagorean theorem. The hypotenuse is 122 inches and one of the cathetus is 120 inches. You clear the other cathetus in the equation and that's it.

I suggest you to do a diagram to guide yourself. Draw a line and let the points at the end to be Phoebe and Tucker locations. Then with help of a protactor, draw the line whether the angle is formed. Check by yourself who is closer, or try it on real life, see an object and ...
