Answer:
False
Step-by-step explanation:
Since, we are given that the STL is a plane and also Z is a plane, then according to geometry, their intersection will give a line. Since, VTX is also a plane according to the figure given, therefore, intersection of the two planes that is STL and Z will give a line and not the plane VTX. Therefore, plane STL and plane Z will not intersect at VTX.
Hence, the given statement is false.
