Geometry in the real world project.

1. GeometricObjects By: Connor Zalesak Block 5 P-AP Geometry

2. Point Names a location Has no size Represented by a dot

3. Line Straight path Has no thickness Extends forever There is one between any two points

4. Plane Flat surface Has no thickness Extends forever

5. Angle A figure formed from two rays with a common endpoint

6. PerpendicularLines Intersect at a 90 degree angle

7. Parallel Lines Never intersect Extend forever

8. Triangle Three sided polygon 180 degrees

9. RightTriangle Three sided polygon 180 degrees The two “legs” make a right angle

10. Pentagon Five sided polygon 540 degrees

11. Hexagon Six sided polygon 720 degrees

12. Square Four sided polygon 360 degrees Every side and angle is congruent

13. Rectangle Four sided polygon 360 degrees The sides parallel to each other are the same length All angles are congruent

14. Trapezoid Four sided polygon 360 degrees Top and bottom are parallel, sides aren’t

15. Parallelogram Four sided polygon 360 degrees Opposite sides are parallel Opposite angles are congruent

16. Circle The side is always one set distance from the center 360 degrees No angles

17. Cylinder 3-dimensional figure 2 Parallel congruent base ends are circles Curved lateral surface connects bases

18. Sphere The side is always one set distance from the center One smooth curved lateral surface

19. Dodecahedron Twelve-sided 3-d figure Made of pentagons 3 faces meet at each vertex

20. Decahedron 10 sided 3-d figure Made of triangles

21. Cube Six- sided 3-d figure All sides, angles, and edges are congruent
