Who told king Ptolemy that if he wanted to truly understand plane geometry he would have to study hard?
The mathematician Euclid is traditionally credited with advising King Ptolemy that to truly understand plane geometry, he would need to study diligently. This anecdote highlights Euclid's emphasis on the importance of rigorous study and mastery of fundamental concepts in mathematics. Euclid's work, notably "The Elements," serves as a foundational text in geometry, illustrating principles through logical deductions.

Did Eratosthene write elements about plane geography?
No, Eratosthenes did not write "Elements" about plane geometry. He is known for his work in fields such as geography and astronomy, particularly his calculation of the Earth's circumference. The "Elements" was a mathematical work by Euclid that focused on geometry.
A line in riemann's sperical geometry is called a?
A line in Riemann's spherical geometry is called a great circle, which is the intersection of a sphere with a plane passing through its center. Great circles are the equivalent of straight lines in this non-Euclidean geometry.
What molecular geometry is characherized by both 120 and 90 bond angles?
The molecular geometry characterized by both 120° and 90° bond angles is known as trigonal bipyramidal. In this arrangement, three atoms are positioned in a plane at 120° angles to each other, while two other atoms are placed above and below this plane, forming 90° angles with the planar atoms. This geometry is typically seen in molecules with five regions of electron density around a central atom, such as phosphorus pentachloride (PCl₅).
What is the molecular geometry of PF5?
3 bonding pairs between P and 3x F atoms.1 free pair at central P atom.3 free pairs on each of the F atoms.Cf in 'Related links' below this answer page
What does sketch plane means?
A sketch plane refers to a flat surface in 3D modeling or computer-aided design (CAD) where a user can create 2D sketches. It serves as a reference for defining geometry, such as lines, arcs, and shapes, which can later be extruded or revolved into three-dimensional objects. The sketch plane can be oriented in various directions and is essential for accurately defining the features of a model.
In Geometry does a plane have edges?
No because in Geometry, a plane goes on infinitely. No because in Geometry, a plane goes on infinitely.
What is a two dimensional object in geometry?
Two dimensional geometry is called "plane geometry" meaning that it occurs on a single surface or plane. The objects used in plane geometry are called plane figures.
What are the example of plane in geometry?
An example is the Cartesian plane where coordinated geometry is plotted

What are the Top two types of geometry?
Plane Geometry and Solid Geometry
What is the difference between a plane geometry and a solid geometry?
one is plane and one is solid
What is plain geometry?
Presumably it is simply geometry. However, plane geometry is geometry which is limited to objects with up to two dimensions, that is, objects that lie in a plane - or on a flat surface.
What was the difference between solid analYtic geometry and plane analYtic geometry?
solid geometry deals with 3 dimensional figures while plane geometry deals with 2 dimensional.
What is non euclidean?
Geometry that is not on a plane, like spherical geometry
