 Question 272094: Hi I'm working with Isosceles triangles. I have (-9,-8) (-4,10)and (-4,-8) I think this is an Isosceles because the lengths of 2 sides are the same. Is this correct? Also, is the length of the base 5? And lastly I need to figure out the area. I've been using the midpoint formula and am getting (-4,1) is this correct? I'm then using the 1st point and the midpoint to plug into the distance formula. I'm getting 106 under a square root sign.....Do I then use 10.29 to plug in the Area formula? I'm trying A= 1/2 (base)5 (height) 10.29=25.73...I don't think I'm supposed to end up with a decimal. Please help me find where I'm going wrong. Thanks Rachel Click here to see answer by Alan3354(30993)
