    Formula for Area of a triangle in 3D??

    Hello,

    I have three points in 3-dimensional space (and cartesian x,y,z coordinates). Can somebody please tell me the formula for finding out the AREA of the triangle formed by them?

    Thanks a lot in advance.

    Use Heron's Formula. You only need the three side lengths, and those are easy.
    All the buzzt!
