In elementary geometry, a polytope is a geometric object with "flat" sides. It is a generalisation in any number of dimensions of the three-dimensional polyhedron. Polytopes may exist in any general number of dimensions nas an n-dimensional polytope or n-polytope.

### Polytopes is a topic in .....?

• A.

Mathematics

• B.

Music

• C.

History

• D.

Philosophy

A. Mathematics
Explanation
Polytopes is a topic in mathematics. Polytopes are geometric figures that exist in any number of dimensions. They are defined as the convex hull of a finite set of points in Euclidean space. The study of polytopes involves understanding their properties, classifications, and relationships with other geometric objects. This topic is an important part of geometry and is extensively studied in mathematics.

### Polytopes is a topic under .....?

• A.

Discrete geometry

• B.

Convex geometry

• C.

Digital geometry

• D.

Toric geometry

A. Discrete geometry
Explanation
Polytopes is a topic under discrete geometry. Discrete geometry is a branch of mathematics that deals with geometric objects that have a finite number of points. Polytopes are a type of geometric object that are defined as the convex hull of a finite set of points in a Euclidean space. Therefore, polytopes fall under the study of discrete geometry.

Two

• B.

Three

• C.

One

• D.

Five

B. Three
Explanation
Polytopes in more than three dimensions were first discovered. This indicates that the study of polytopes began with three-dimensional shapes and then expanded to higher dimensions.

### Polytopes in more than three dimensions were first discovered by?

• A.

Ludwig Schläfli

• B.

Albert Einstein

• C.

Isaac Newton

• D.

James McCafrrey

A. Ludwig Schläfli
Explanation
Ludwig Schläfli is credited with the discovery of polytopes in more than three dimensions. He was a Swiss mathematician who made significant contributions to the field of geometry. Schläfli's work on polytopes laid the foundation for the study of higher-dimensional shapes and their properties. His discoveries and mathematical formulations have had a lasting impact on the field of geometry and continue to be studied and built upon by mathematicians today.

### The word polytop is a term from which country?

• A.

England

• B.

U.S.A

• C.

Germany

• D.

China

C. Germany
Explanation
The word "polytop" is a term that originated in Germany. This suggests that the concept or idea of a polytop, which refers to a geometric shape with flat sides and straight edges in any number of dimensions, was first developed or popularized in Germany.

A. Reinhold Hoppe
Explanation
The correct answer is Reinhold Hoppe. He is the mathematician who coined the German term "polytop".

### The German term polytop was coined by the mathematician Reinhold Hoppe, and was introduced to ....... mathematicians as polytope.

• A.

Austrian

• B.

England

• C.

Chinese

• D.

American

B. England
Explanation
The German term "polytop" was introduced to English mathematicians as "polytope". This suggests that the term originated in Germany and was then adopted by English mathematicians. Therefore, the answer is England.

### The German term polytop was coined by the mathematician Reingold Hoppe, and was introduced to English mathematicians as polytope by .....?

• A.

Alicia Boole Stott

• B.

Isaac Newton

• C.

Albert Einstein

• D.

James McCafrey

A. Alicia Boole Stott
Explanation
Alicia Boole Stott is the correct answer because she was a mathematician who made significant contributions to the field of geometry, particularly in the study of polytopes. She was the first to introduce the term "polytope" to English mathematicians, which was originally coined by Reingold Hoppe, a German mathematician. Therefore, Stott played a crucial role in bringing this term into the English mathematical literature.

### Polytopes can be put into how many important classes?

• A.

3

• B.

A. 3
Explanation
Polytopes can be put into three important classes. This suggests that there are three distinct categories or classifications that polytopes can fall into. Without further information, it is not possible to determine what these classes are specifically, but it can be inferred that there are three significant types or groupings of polytopes.

• D.

1

B. 3
Explanation
Polytopes have three generalizations. A polytope is a geometric figure with straight sides in any number of dimensions. The three generalizations of polytopes are: 1) Convex polytopes, which are polytopes with all interior angles less than 180 degrees; 2) Non-convex polytopes, which are polytopes with at least one interior angle greater than 180 degrees; and 3) Abstract polytopes, which are combinatorial structures that generalize the concept of polytopes to include more abstract properties such as face lattice and incidence relations.
