... A 2-dimensional subspace in 4-space is just a plane in 4-space that passes through the origin. How can two planes intersect? In 3-space, your experience gives the answer. If they’re not the same plane, then they must intersect in a line. (They have the origin in common, so they can’t be parallel.) V ...
