1. Geometry in the Real World By: Matthew Dickey 1st 1

2. Point Point- It names a specific location and has no size This is a nail hammered into a wall in the garage 2

3. Line (segment) Line segment- A straight path that has no thickness and extends forever This is a picture of a highway road stripe 3

4. Plane Plane- Flat surface that has no thickness and extends forever This is a football field enzone and the surface of the field is a plane 4

5. Angle Angle- A figure formed by two rays with a common endpoint This is a door frame that forms a 90 degree angle 5

6. Perpendicular lines Perpendicular lines- Intersecting lines that form 90 degree angles The bars on this fence form 90 degree angles to one another 6

7. Parallel Lines Parallel lines- Lines in the same plane that don’t intersect These tube rails on a road bridge are parallel to each other 7

8. Triangle Triangle- A three sided polygon This is a TV tray and the legs form a Triangle. 8

9. Right Triangle Right Triangle- A triangle with one 90 degree angle This is a power pole and the Wire, brace, and pole make up a right triangle 9

10. Pentagon Polygon- A five sided polygon This is a crosswalk sign that forms a Pentagon 10

11. Hexagon Hexagon- A six sided polygon These are hexagon shaped pavestones 11

12. Square Square- Quadrilateral with four congruent sides and four right angles This is a Road work sign that is a square 12

13. Rectangle Rectangle- A quadrilateral with four right angles This is a street sign that forms a rectangle 13

14. Trapezoid Trapezoid- A quadrilateral with exactly one pare of parallel sides This is a bank sign that is a trapezoid 14

15. Parallelogram Parallelogram- A quadrilateral with two pairs of parallel sides This is the Arby’s logo and it forms a parallelogram 15

16. Circle The set of points that are in a plane that are a fixed distance from a given point This is a big clock on a tower that forms a circle 16

17. Cylinder Cylinder- A three dimensional figure with Two parallel congruent circular bases and a curved lateral surface that connects the bases This is a transformer on a power pole that makes a cylinder 17

18. Sphere Sphere- The set of all points in space that are fixed distance from a given point This is a sphere shaped light bulb cover 18

19. Octagon Octagon- An eight sided polygon This is a stop sign that forms a octagon 19

20. Cone Cone- A three dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex This is the top of a lava lamp that forms a cone 20

21. Cube Cube- A prism with six square faces This is a Rubik cube that forms a cube 21
