Maekawa's theorem states that at any vertex the number of valley and mountain folds always differ by?
-
One
-
Two
-
Three
-
Zero
Correct Answer
A. TwoExplanation
Maekawa's theorem states that at any vertex, the number of valley and mountain folds always differ by two. This means that if there are x valley folds at a vertex, there will be x+2 mountain folds. This theorem is important in origami and paper folding as it helps ensure that the folds are balanced and allows for the creation of more complex and intricate designs.Rate this question:

Kawasaki's theorem states that at any vertex, the sum of all the odd angles adds up to?
-
360 degrees
-
90 degrees
-
270 degrees
-
180 degrees
Correct Answer
A. 180 degreesExplanation
Kawasaki's theorem states that at any vertex, the sum of all the odd angles adds up to 180 degrees. This means that if we have a polygon with multiple vertices, and we sum up all the odd angles at each vertex, the total will always be 180 degrees. This theorem is a useful tool in geometry to calculate the sum of angles in polygons.Rate this question:

In the flat folding of a pure origami, a sheet can never penetrate a?
-
Fold
-
Pattern
-
Crease
-
Line
Correct Answer
A. FoldExplanation
In the flat folding of a pure origami, a sheet can never penetrate a fold. This is because a fold in origami refers to the act of bending the paper along a specific line, creating a crease. The fold acts as a barrier, preventing the sheet from going through it. Therefore, a sheet of paper cannot penetrate a fold in origami.Rate this question:

The product of principal curvatures of a surface at a point is referred to as?
-
Orion plane
-
Maekwa curvature
-
Saddle surface
-
Gaussian curvature
Correct Answer
A. Gaussian curvatureExplanation
The product of principal curvatures of a surface at a point is referred to as Gaussian curvature. Gaussian curvature is a measure of how the surface curves at a particular point. It is named after Carl Friedrich Gauss, who introduced the concept. The Gaussian curvature can be positive, negative, or zero, indicating different types of curvature at the point. A positive Gaussian curvature indicates a surface that curves outward like a sphere, a negative Gaussian curvature indicates a surface that curves inward like a saddle, and a zero Gaussian curvature indicates a surface that is flat.Rate this question:

What is a function that is its own inverse?
-
Cipher
-
Domain
-
Involution
-
Quaternion
Correct Answer
A. InvolutionExplanation
An involution is a function that when applied twice returns the original input. In other words, if you apply the function to a value and then apply it again to the result, you will get back the original value. This property makes an involution its own inverse. Therefore, an involution is the correct answer to the question.Rate this question:

Which is not an example of impossible construction of geometric figures?
-
Squaring the circle
-
Heptadecagon
-
Doubling the cube
-
Angle trisection
Correct Answer
A. HeptadecagonExplanation
A heptadecagon is a polygon with 17 sides, and it is possible to construct it geometrically. Squaring the circle, doubling the cube, and angle trisection, on the other hand, are examples of geometric constructions that have been proven to be impossible using only a compass and straightedge.Rate this question:

A rigid fold that has been used to deploy large solar panel arrays for space satellites is the?
-
Cut fold
-
Napkin fold
-
Miura map fold
-
Wet fold
Correct Answer
A. Miura map foldExplanation
The Miura map fold is a type of rigid fold that is commonly used to deploy large solar panel arrays for space satellites. This fold allows for compact storage and easy deployment, making it ideal for space applications. It is often used because it can be easily unfolded and locked into place, providing a stable and rigid structure for the solar panels to capture sunlight efficiently.Rate this question:

The problem of whether a square or rectangle of paper can be folded so the perimeter of the flat figure is greater than that of the original square is the?
-
Napkin folding problem
-
Wet folding
-
Fold-and-cut problem
-
Galllivan problem
Correct Answer
A. Napkin folding problemExplanation
The napkin folding problem refers to the challenge of folding a square or rectangle of paper in such a way that the perimeter of the resulting flat figure is greater than that of the original square. This problem is often encountered in the context of decorative napkin folding, where individuals try to create intricate and visually appealing shapes out of napkins. By exploring different folding techniques, one can potentially achieve a higher perimeter for the folded figure, making it a solution to the napkin folding problem.Rate this question:

Which origami folding allows for a greater range of shapes?
-
Wet
-
Cut
-
Napkin
-
Sheet
Correct Answer
A. WetExplanation
Wet origami folding allows for a greater range of shapes because when the paper is wet, it becomes more pliable and easier to manipulate. This allows for more intricate and complex folds to be made, resulting in a wider variety of shapes that can be created.Rate this question:
