Question

Why is the pointed arch seen in Gothic architecture structurally more stable than the rounded arch used earlier?

Answer 1

It's pointed arch helps it support the weight above it (this subject should be art and not history)

Answer 2

The Gothic architecture is usually seen, in the church and cathedral. The pointed arch in the Gothic architecture structurally allows more stable than the rounded arch because the pointed arch provided less thrust on the base and it allowed the structures to be taller and the columns to be more slender. The new style of architecture allowed for vaulting and ornamentation in a cathedral.
