Why does the video call the same geometry spherical or elliptical?

Conditions

• The geometry has a positively curved surface.
• The context is the introductory naming convention used in the video.

Reasoning, step by step

1. Identify the geometry being discussed as having positive curvature.
2. Note the on-screen title "SPHERICAL GEOMETRY".
3. Listen to the narration stating it is also called elliptical geometry.
4. Conclude that both terms refer to the same positively curved framework in this context.

Example

The narration says, "It is also called spherical or elliptical geometry," while the on-screen title reads "SPHERICAL GEOMETRY" and a wireframe globe is shown.

Common misconceptions

• Assuming that spherical and elliptical geometries are fundamentally different concepts.
• Believing that elliptical geometry refers to the geometry of an ellipse rather than a positively curved space.
