Constructions in Geometry

In Geometry, we are required to complete activities called "constructions." It is basically copying segments, angles, and shapes with only using a compass and straightedge, like how the Greeks did it. The Greeks did constructions all the time. The mathematician, Euclid, who lived around 330 B.C. - 260 B.C, published a book called "Elements" which contains the constructions my peers and I use in math class today. He is called the father of Geometry. One reason the Greeks had constructions is that they only had whole numbers and no decimals. If they needed to find a midpoint, they could not measure it, so they would have to construct it. Thanks to the Greeks, we get to do fun activities in math class.
