• 1. Geometry in the Real World! Sam Lassiter Period-5

2. Point!

• Definition: Apointis an exact position or location on a plane surface.

3. Line!

• Definition: Aline segmentis a part of a line that is bounded by two end points, and contains every point on the line between its end points.

4. Plane!

• Definition: A surface containing all the straight lines that connect any two points on it.

5. Angle!

• Definition: A shape, formed by two lines or rays diverging from a common point.

6. Perpendicular Lines!

• Definition: Two lines that intersect to form a 90 degree angle.

7. Parallel Lines!

• Definition: Parallel lines remain the same distance apart over their entire length.

8. Triangle!

• Definition: A three sided polygon.

9. Right Triangle!

• Definition: Aright triangleis where there are two 45 degrees angles and one 90 degree.

10. Pentagon!

• Definition: A plane figure having five angles, and consequently, five sides; any figure having five angles.

11. Hexagon!

• Definition: A polygon with 6 sides.

12. Square!

• Definition: A plane figure having equal sides.

13. Rectangle!

• Definition: Arectangleis a four-sided polygon where every angle is a right angle.

14. Trapezoid!

• Definition: A quadrilateral having two parallel sides.

15. Parallelogram!

• Definition: Opposite sides are parallel and equal in length, and opposite angles are equal.

16. Circle!

• Definition: A plane curve everywhere equidistant from a given fixed point, the center.

17. Cylinder!

• Definition: An object or shape with straight sides and circular ends of equal size.

18. Sphere!

• Definition: A three-dimensional surface, all points of which are equidistant from a fixed point.

19. Octagon!

• Definition: A plane figure with eight angles and eight sides.

20. Polygon!

• Definition: A closed plane figure bounded by three or more line segments.

21. Parabola!

• Definition: A plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone or by the locus of points equidistant from a fixed line and a fixed point not on the line.
