Math Project

1. 1. Geometry in the Real World <ul><li>Clay Hearrean </li></ul><ul><li>Block 2 </li></ul><ul><li>December 11, 2009 </li></ul>
2. 2. Point <ul><li>Exact position or location on a plane surface. </li></ul><ul><li>The middle of the home plate is a point. </li></ul>
3. 3. Line (Segment) <ul><li>A line with definite endpoints. </li></ul><ul><li>In football, receivers try to stay in bounds- the boundaries are a line segment. </li></ul>
4. 4. Plane <ul><li>An imaginary flat surface that is infinitely large and with zero thickness. </li></ul><ul><li>The bowling alley is a flat surface. </li></ul>
5. 5. Angle <ul><li>A shape formed by two lines or rays diverging from a common point (the vertex). </li></ul><ul><li>The field goal makes 2 90 degree angles. </li></ul>
6. 6. Perpendicular Lines <ul><li>A line is perpendicular to another if it meets or crosses it at right angles (90 degrees). </li></ul><ul><li>The net makes perpendicular lines with the service boxes. </li></ul>
7. 7. Parallel Lines <ul><li>Lines are parallel if they lie in the same plane and are the same distant apart over their entire length. </li></ul><ul><li>Each yard line of a football field is parallel with the previous or next yard line. </li></ul>
8. 8. Triangle <ul><li>A closed figure consisting of three line segments linked end to end, 3 sided polygon. </li></ul><ul><li>A baseball diamond’s infield cut in half is a triangle. </li></ul>
9. 9. Right Triangle <ul><li>A triangle where one of its interior angles is a right angle (90 degrees). </li></ul><ul><li>The 10 area of the shuffle board cut in half is 2 right triangles. </li></ul>
10. 10. Pentagon <ul><li>A polygon with 5 sides. </li></ul><ul><li>Most soccer balls have pentagons on them. </li></ul>
11. 11. Hexagon <ul><li>A polygon with 6 sides. </li></ul><ul><li>MMA fighters fight in hexagon rings. </li></ul>
12. 12. Square <ul><li>A 4-sided regular polygon with all sides equal and all internal angles 90 degrees. </li></ul><ul><li>1st base is a square. </li></ul>
13. 13. Rectangle <ul><li>A 4-sided polygon where all interior angles are 90 degrees. </li></ul><ul><li>A football field is a rectangle. </li></ul>
14. 14. Trapezoid <ul><li>A quadrilateral which has at least one pair of parallel sides. </li></ul><ul><li>In an Oklahoma drill 2 trapezoidal pads are used as boundaries. </li></ul>
15. 15. Parallelogram <ul><li>A quadrilateral with both pairs of opposite sides parallel and equal in length. </li></ul><ul><li>This guitar’s frets have parallelograms on them. </li></ul>
16. 16. Circle <ul><li>A line forming a closed loop, every point on which is a fixed distance from a center point. </li></ul><ul><li>In hockey arenas, center ice is a circle. </li></ul>
17. 17. Cylinder <ul><li>A solid with circular ends and straight sides (like a pipe). </li></ul><ul><li>The sweet spot of a baseball bat has the shape of a cylinder. </li></ul>
18. 18. Sphere <ul><li>A 3-dimensional object shaped like a ball. Every point on the surface is the same distance from the center. </li></ul><ul><li>A golf ball is a sphere. </li></ul>
19. 19. Octagon <ul><li>A polygon with 8 sides. </li></ul><ul><li>UFC fighters fight in octagon cages. </li></ul>
20. 20. Oval <ul><li>An oval or ovoid is any curve that looks like an egg or an ellipse. It is not a precise term and there are many curves that get called &quot;oval&quot;. </li></ul><ul><li>A NASCAR track is an oval. </li></ul>
21. 21. Isosceles Triangle <ul><li>A triangle which has 2 of its sides equal in length. </li></ul><ul><li>A dartboard has many isosceles triangles. </li></ul>
