Exam-Style Question on Voronoi DiagramA mathematics exam-style question with a worked solution that can be revealed gradually |
Question id: 438. This question is similar to one that appeared on an IB AI Standard paper (specimen) for 2021. The use of a calculator is allowed.
Points A (-1 , -1) , B (-3 , 1) , C (1 , -3) , D (3 , 1) and E (-3 , -3) represent the locations of toilet buildings on a large caravan site. These points are illustrated on the following coordinate axes.
Horizontal scale: 2 units represents 1 km.
Vertical scale: 2 units represents 1 km.
(a) Calculate the gradient of the line segment AD.
The Site Manager draws three straight lines to form an incomplete Voronoi diagram.
(b) Find the equation of the line which would complete the Voronoi cell containing site A. Give your answer in the form \(ax + by + d = 0\) where \(a , b , d \in \mathbb Z \).
(c) In the context of the question, explain the significance of the Voronoi cell containing site A.

The worked solutions to these exam-style questions are only available to those who have a Transum Subscription. Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves. This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures. A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience. |
