4.
Tangram was introduced to Germany by?
Correct Answer
C. Friedrich Adolf Richter
Explanation
Friedrich Adolf Richter is the correct answer because he was a German mathematician and educator who is credited with introducing Tangram to Germany in the early 19th century. He saw the educational value of Tangram as a tool for teaching geometry and spatial reasoning skills, and he popularized it among students and teachers in Germany. His efforts helped to spread the use of Tangram as a recreational and educational puzzle throughout Europe and eventually to other parts of the world.

A tangram paradox is called a?
Correct Answer
D. Dissection fallacy
Explanation
A tangram paradox refers to a situation where a tangram puzzle seems to defy logic or common sense. In this context, a "dissection fallacy" would be an appropriate term to describe such a paradox. The term "dissection" implies that the tangram pieces are being rearranged or dissected in a way that creates a paradoxical outcome. The term "fallacy" suggests that the paradox is based on a false or misleading reasoning. Therefore, "dissection fallacy" is the most suitable explanation for the given correct answer.
6.
A figure which does not change upon undergoing a reflection has a?
Correct Answer
B. Reflectional symmetry
Explanation
Reflectional symmetry refers to the property of a figure or object that remains unchanged when reflected over a line or plane. In other words, if a figure has reflectional symmetry, it means that it can be divided into two equal halves that are mirror images of each other. This implies that the figure looks the same before and after the reflection, indicating that it does not change upon undergoing a reflection. Therefore, the answer "reflectional symmetry" is the correct explanation for the given question.

The 14-piece puzzle Ostomachion is also known as?
Correct Answer
A. Loculus Archimedius
Explanation
The 14-piece puzzle Ostomachion is also known as "loculus Archimedius."
8.
Which is an example of a tiling puzzle?
Correct Answer
C. Tantrix
Explanation
Tantrix is an example of a tiling puzzle. Tiling puzzles involve arranging geometric shapes to completely cover a given area without any overlaps or gaps. Tantrix is a puzzle game that uses hexagonal tiles with different colored lines on them. The goal is to connect the tiles in a way that matches the colors on the lines, creating a continuous loop. This requires strategic thinking and spatial reasoning skills, making it a classic example of a tiling puzzle.
9.
The conway puzzle is based on?
Correct Answer
C. Parity
Explanation
The Conway puzzle is based on parity. Parity refers to the property of a mathematical object being either even or odd. In the context of the Conway puzzle, it likely refers to the concept of parity in the arrangement and movement of game pieces. The puzzle may involve determining and manipulating the parity of certain configurations to solve it.

How many polycubes make up the bedlam cube?
Correct Answer
A. 13
Explanation
The bedlam cube is a 3D puzzle consisting of various polycubes, which are three-dimensional shapes made up of smaller cubes. The question asks how many polycubes make up the bedlam cube, and the correct answer is 13. This means that the bedlam cube is made up of 13 different polycubes, each with its own unique shape and arrangement of smaller cubes.
