Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the geometric systems?Encompasses hyperbolic geometry (constant negative curvature) and elliptic geometry (constant positive curvature)
2. What is the modern applications?Used in navigation (great circle routes), computer graphics, and advanced differential geometry

Parallel Postulate: Euclid's fifth axiom, stating that exactly one line through a point is parallel to a given line.
Hyperbolic Geometry: A geometry characterized by constant negative curvature, where parallel lines diverge.
Elliptic Geometry: A geometry characterized by constant positive curvature, where all lines intersect.
Spacetime Curvature: The warping of the four-dimensional fabric of spacetime by mass and energy, as described by general relativity.
