\n" );
document.write( "I'm working with Isosceles triangles. I have (-9,-8) (-4,10)and (-4,-8)
\n" );
document.write( "I think this is an Isosceles because the lengths of 2 sides are the same. Is this correct?\r
\n" );
document.write( "\n" );
document.write( "Also, is the length of the base 5?
\n" );
document.write( "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.

Is this correct? \n" ); document.write( "It's not isosceles, there are no 2 equal sides. \n" ); document.write( "It is a right triangle. \n" ); document.write( "-------------------------- \n" ); document.write( "Also, is the length of the base 5? \n" ); document.write( "The base is 5, from (-9,-8) to (-4,-8) \n" ); document.write( "---------------------------------------- \n" ); document.write( "And lastly I need to figure out the area.
