Final answer:
The invention of the pointed arch in Gothic architecture had a profound impact on the construction of cathedrals. It allowed for taller buildings with larger windows and more light. The pointed arch also reduced the need for thick walls, creating spacious and open interiors.
Step-by-step explanation:
The invention of the pointed arch had a significant effect on the building of cathedrals in the Gothic period. Pointed arches allowed for greater height and larger windows, giving cathedrals a sense of grandeur and allowing more light to enter the buildings. Additionally, the pointed arch transferred the weight of the structure more efficiently, reducing the need for thick walls and allowing for more open and spacious interiors.
