Statement 1:Let `A( vec a),B( vec b)a n dC( vec c)` be three points such that ` vec a=2 hat i+ hat k , vec b=3 hat i- hat j+3 hat ka n d vec c=- hat i+7 hat j-5 hat kdot` Then `O A B C` is a tetrahedron.
Statement 2: Let `A( vec a),B( vec b)a n dC( vec c)` be three points such that vectors ` vec a , vec ba n d vec c` are non-coplanar. Then `O A B C` is a tetrahedron where `O` is the origin.
