What Do You Know About The Carpenters Problem? - Quiz

In the carpenter's problem, you are to provide answers on the likelihood of a simple polygon being moved to a point where all vertices are convex when the length of the edges is properly established. The problem became popular following attempts by mathematicians to solve it in the 21st century. How conversant are you with geometry problems? Do not be found wanting!

    • A. 

      2013

    • B. 

      2014

    • C. 

      2015

    • D. 

      2017

  • 3. 

    Which part of the shape is most concerned in the solution by Strianu and Whiteley?

    • A. 

      Edges

    • B. 

      Vertex

    • C. 

      Segment

    • D. 

      Angle

    Correct Answer
    B. Vertex
    Explanation
    The solution by Strianu and Whiteley is most concerned with the vertex of the shape. This means that they focus on the point where two or more edges of the shape meet. They likely analyze the properties and characteristics of the vertex to find a solution to the problem at hand.

  • 4. 

    In this problem, what change has an effect on the Jordan curve?

    • A. 

      It is made concave

    • B. 

      It is made convex

    • C. 

      It is curved

    • D. 

      It is straightened

    Correct Answer
    B. It is made convex
    Explanation
    When the Jordan curve is made convex, it means that the curve is bent outward, creating a shape that does not intersect itself. This change in curvature affects the overall shape of the curve, making it more open and allowing for a larger area to be enclosed by the curve.

    Which is the term for the continuous transformation of a closed curve in the plane and eventually convexifying it?

    • A. 

      Curve shortening flow

    • B. 

      Flow convexing

    • C. 

      Convexing

    • D. 

      Concave flow

    Correct Answer
    A. Curve shortening flow
    Explanation
    Curve shortening flow refers to the continuous transformation of a closed curve in the plane, where the curve is gradually shortened and eventually becomes convex. This process involves the curve evolving over time by shrinking and smoothing out any concave regions, resulting in a convex shape. Therefore, curve shortening flow is the appropriate term for this phenomenon.

    How many sides should be observable in an ideal trapezium?

    • A. 

      3 sides

    • B. 

      10 sides

    • C. 

      8 sides

    • D. 

      6 sides

    Correct Answer
    D. 6 sides
    Explanation
    An ideal trapezium should have 6 sides. A trapezium is a quadrilateral with one pair of parallel sides. The other two sides are non-parallel and can have any length. So, in an ideal trapezium, there are 4 sides that form the quadrilateral shape, and 2 additional sides that are parallel to each other. Therefore, a total of 6 sides should be observable in an ideal trapezium.
