Pre-Ap Geometry Project

1. Geometry in the Real World Project Matt Campos Mrs. Sykes Block (4)

2. Point A geometric element that has zero dimensions and a location determinable by an ordered set of coordinates.

3. Line (Segment) The portion of a line that lies strictly between two point.

4. Plane A two-dimensional group that goes infinitely in all directions.

5. Angle The union of two rays that have a common endpoint. Angles are measured in degrees.

6. Perpendicular Lines Two segment rays , or lines that intersect two form 90 degree angles.

7. Parallel Lines Two or more co-planer lines that have no points in common and never intersect.

8. Triangle A polygon with three sides whose angles add up to 180 degrees.

9. Right Triangle A triangle with that has an angle of 90 degrees.

10. Pentagon A five-sided polygon

11. Hexagon A six-sided polygon.

12. Square An equilateral and equiangular quadrilateral.

13. Rectangle A quadrilateral whose angles are all right angles.

14. Trapezoid A quadrilateral with at least one pair of parallel lines and a pair of intersecting lines.

15. Parallelogram A quadrilateral with both pairs of opposite side parallel.

16. Circle the set of points on a plane at a certain distance radius from a certain point center; a polygon with infinite sides.

17. Cylinder A solid bounded by two parallel planes and such a surface, especially such a surface having a circle as its base.

18. Sphere The set of points in space equidistant from a certain point

19. Octagon An eight-sided polygon

20. Cone The surface of a conic solid whose base is a circle.

21. Acute Angle An angle whose measure is greater than 0 but less than 90 degrees. …the roof
