Transcript

  • 1. Geometry In The Real World Kyle Grey Block 2
  • 2. Point- A precise location or place on a plane.
  • 3. Line Segment-straight line which links two points without extending beyond them.
  • 4. Plane-An imaginary flat surface that is infinitely large and with zero thickness
  • 5. Angle-formed by two lines or rays diverging from a common point
  • 6. Perpendicular lines-A line that crosses at a right angle
  • 7. Parallel lines-Lines that are always the same distance apart and will never meet.
  • 8. Triangle-A closed figure consisting of three line segments linked end-to-end
  • 9. Right Triangle-A triangle where one of its interior angles is a right angle
  • 10. Pentagon-A polygon with 5 sides
  • 11. Hexagon-A polygon with 6 sides
  • 12. Square-A 4-sided regular polygon with all sides equal and all internal angles 90°
  • 13. Rectangle-A 4-sided polygon where all interior angles are 90°
  • 14. Trapezoid-A quadrilateral which has at least one pair of parallel sides 
  • 15. Parallelogram-A quadrilateral with opposite parallel lines
  • 16. Circle-A line forming a closed loop, every point on which is a fixed distance from a center point.
  • 17. Cylinder-A surface generated by a straight line moving parallel to a fixed straight line and intersecting a plane curve.
  • 18. Sphere-A three-dimensional surface, all points of which are equidistant from a fixed point.
  • 19. Octagon-A polygon with 8 sides
  • 20. Oval-any curve that looks like an egg or an ellipse. 
  • 21. Rectangular Prism- object which has six faces that are rectangles.
