1. Geometry in the Real world Madison Davis Blk 2

2. Point Something that has position, but not extension, such as the converging point of two lines.

3. Line (Segment) A straight figure that has a defined ends. Unlike a line which extends forever.

4. Plane A flat, level surface. A surface generated by a straight line moving at constant velocity with respect to a fixed point.

5. Angle The space within two lines(or line segments) or three or more planes diverging from a common point.

6. Perpendicular Lines Line or line segments that intersect each other at a 90 degree angle.

7. Parallel Lines Line or line segment that never intersect, ever.

8. Triangle A closed plane figure with three sides and three angles which always add up to 180 degrees.

9. Right Triangle A closed plane figure with three sides and three angles, however one of the angles must always be 90 degrees.

10. Pentagon A closed plane polygon with 5 sides and 5 angles which add to 540 degrees.

11. Hexagon A closed plane figure with 6 sides and 6 angles which add to 720 degrees.

12. Square A closed place figure with 4 equal sides and 4 90 degree angles.

13. Rectangle A closed plane figure with 4 sides and 4 90 degree angles.

14. Trapezoid A quadrilateral figure with two parallel lines and two non parallel lines.

15. Parallelogram A quadrilateral figure having both pairs of opposite sides parallel to each other.

16. Circle A closed plane curve consisting of all given points at a distance from the center. Equation: x^2 + y^2 = r^2

17. Cylinder A surface or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes.

18. Sphere A solid figure generated by the revolution of a semicircle about it’s diameter.

19. Cube A solid bounded by six equal squares, the angle between any two adjacent faces being right.

20. Cone A solid whose surface is generated by a line passing through a fixed point and a fixed plane curve not containing the point, consisting of two equal sections joined at a vertex.

21. Pyramid A solid having a polygonal base and triangular sides which meet at one point.
