Most famous medieval cathedrals are in Europe (where the Christians were), and they were built between about 1000 and 1600 AD, during the Middle Ages. There are cathedrals all over Europe, in Spain, in England, in France, in Germany, and in Italy. The architecture of cathedrals is based on the old Roman basilica.

Yup! The midpoint between two points is just the average of the x-coordinates and the average of the y-coordinates. Let's look at a few more examples to illustrate that point. For example, in the graph below, the yellow dot is again located at the midpoint between two red points. Those points are located at (3,5) and (-4,-9). Their midpoint is located at (-.5, -2): Let's look at a quick example algebraically if you're not clear yet: Example 1: Find the point halfway between \((0,3)\) and \((4,7)\): Remember the midpoint formula: $$ (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}) $$ Plug in the appropriate values:
