Re: Triangle

Triangles T-2 can be obtained from T-1 by the following procedure:

Draw T-1 in the XY plane. Orient b on the + X-axis. Now to obtain T-2
extend b in the negative X-direcrion and keep the magnitude the same.
Now from one end of "-b" draw an arc of length "c" and from the other
end draw an arc of length "a".
Now by joining the intersection point to the two ends of "-b" one
obtains triangle T-2.
This is how one obtains T-2 from T-1.
If not clear ask for additional questions until you are fully satisfied.
