Question 272094
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?
It's not isosceles, there are no 2 equal sides.
It is a right triangle.
--------------------------
Also, is the length of the base 5?
The base is 5, from (-9,-8) to (-4,-8)
----------------------------------------
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.
----------------------------------------------
The area is bh/2 = 5*18/2 = 45 square units
