Circumcentre angle bisector As part of their fundraising for Right To Play, the student council is having a fun-fair at lunch in the school yard. You will be running three events at different locations: a basketball foul-shot contest, a mini-putt course and a dunk-tank. Your job is to locate the ticket booth so that it will be the same distance from each of the events. Describe the process you would use to determine the position of the ticket booth. Create a GeoGebra design that supports your decision. The centre of a triangle must always be found inside the triangle. Illustrate the statement with examples or deny the statement using counter-examples. A diagram would be helpful in supporting your opinion. Assuming the triangle was made of a material of uniform thickness, which of the centres would also be the centre of gravity of the triangle? Support your choice.
