Zoë Hornberger Line Intersection Postulate: Hurdles are an event in track; a hurdle is comprised of a bar that is held up by two supports. The Line Intersection postulate is that if two lines intersect, their intersection is exactly one point. Since a hurdle is a bar supported by two posts, there is two intersections and two examples of the Line Intersection postulate. The concept of hurdles is a demonstration of two intersection points between lines; thus, geometry is fundamental to track because the composition of a hurdle is entirely dependent on the Line Intersection postulate. Right Angles: Right angles are a key component in the sprinting, running form. Both the arms and legs are supposed to bend at 90° degree angles, right angles, to increase the momentum and the length of a runner’s…show more content…
The Line Postulate by definition is that through any two points, there is exactly one line. High jump is an event where a person leaps over a bar that is equally supported by two posts. These two points on both side form a straight line. The two equal heights of the posts where the bar is resting demonstrate how a line is formed from two points and, in turn, how the Line Postulate is a key geometric concept that is fundamental to high jump. Symmetry: In track, the physical track requires symmetry in races, depending on the event. Since as the circumference increases as the distance grows farther from the vertex, the race would be unfair because people on the outer lanes would have to run a farther distance. In order to make a race fair, the staggered start method is used; a staggered start makes each individual lane, progressing outward, have a special, increasing distance, so that each runner runs exactly the same distance. This is a fundamental concept in geometry, for the symmetry of the staggered start method allows for each race to be fair. Segment Addition
