WebMar 16, 2024 · Flat Geometry. This is the geometry we learned in school. The angles of a triangle add up to 180 degrees, and the area of a circle is π r2. The simplest example of a flat three-dimensional shape is ordinary infinite space — what mathematicians call Euclidean space — but there are other flat shapes to consider too. WebThe earth’s surface is affected by the sun’s rays in the same way. The sun’s rays shine on earth with an intensity of about 1370 Watts per square meter. Even though the sun’s rays hit the earth in parallel beams, the tilt of the earth towards the sun causes the beams to hit more directly in some places than others. WebSince the rotation axis of the earth is inclined to the orbital plane, the ecliptic and equator, represented by great circles on the celestial sphere, cross at two points 180° apart.
