### Transcript

• 1. Geometry in the Real World Welcome to the natatorium! By Sarah Musselman Block 1
• 2. Why a natatorium you might ask?
• Well I spend most of my time at school, but when I’m not at school I am most likely at the natatorium! I am on a diving team called GC Divers which is currently 3 rd in the nation. We practice in Keller, Texas at the KISD Natatorium. So, the point I’m really getting to is being at a natatorium is my world, so here we go!
• 3. Point!
• A point is an undefined term in geometry. It names a location and has no size.
• A point in a natatorium would be the buoy attached to a lane line.
• 4. Line (segment)!
• A line is a straight path that has no thickness and extends forever. (a segment is the line in between two points.)
• A line in a natatorium would be the lane lines.
• 5. Plane!
• A plane is a flat surface that has no thickness and extends forever.
• A plane in a natatorium would be the pool of course! The pool contains pretty much every point in the natatorium.
• 6. Angle!
• An angle is a figure formed by two rays with a common endpoint.
• An example of an angle in a natatorium would be the diving board rails.
• 7. Perpendicular lines!
• Perpendicular lines are lines that intersect at 90 degrees.
• Perpendicular lines at a natatorium are the lines at the bottom of the pool.
• 8. Parallel lines!
• Parallel lines are lines in the same plane that do not intersect.
• Parallel lines in a natatorium would be the tower diving boards!
• 9. Triangle!
• A triangle is a tree-sided polygon.
• A triangle in a natatorium would be the flags going across the pool.
• 10. Right triangle!
• A right triangle is a triangle with one right angle.
• In a natatorium a right triangle is the belting rig that divers use to practice dives onto mats instead of water.
• 11. Pentagon!
• A pentagon is a five sided polygon.
• A pentagon in a natatorium would be the paddles used for training lifeguards.
• 12. Hexagon!
• A hexagon is a six-sided polygon.
• An example would be the weights that the divers use in the weight room at the natatorium.
• 13. Square!
• A square is a quadrilateral with four congruent sides and four right angles!
• A square at the natatorium would be the top of the starting block.
• 14. Rectangle!
• A rectangle is a quadrilateral with four right angles!
• A rectangle at a natatorium would be the GC Divers (My team’s) national championship banner!
• 15. Trapezoid!
• A trapezoid is a quadrilateral with exactly one pair of parallel sides!
• A trapezoid at the natatorium would be the speakers.
• 16. Parallelogram!
• A parallelogram is a quadrilateral with two pairs of parallel sides.
• An example would be the railing of the stairs at the natatorium!
• 17. Circle!
• A circle is a set of points in a plane that are a fixed distance from a given point called the center of a circle.
• A circle in the natatorium would be one of the life saving devices!
• 18. Cylinder!
• A cylinder is a 3-D figure with two parallel congruent circular bases and a curved surface that connects the base.
• An example would be the water buoy that the swimmers use!
• 19. Sphere!
• A sphere is the set of points in a space that are a fixed distance from a given point called the center of the sphere.
• A sphere would be the Swiss workout balls the divers use in training!
• 20. Oval!
• An oval is any curve that looks like an egg or an ellipse.
• An oval in a natatorium would be the hand rail leading up to the 3-meter diving board!
• 21. Pentagram!
• A pentagram is the shape of a five-pointed star with five straight strokes.
• A pentagram in a natatorium is the beloved star that rest above the KISD Natatorium!
• 22. Cone!
• A cone is a 3-D figure with a circular base and a curved lateral surface that connects to a point called the vertex
• A cone in a natatorium would be the workout cones that the divers use to map our sprints!
• 23. Special thanks!
• To Keller ISD natatorium for letting me take pictures there after practice!
• To my coaches Jeff and Krista for letting me take a picture of one of our banners!
• And to the University of Miami at Ohio for letting me get a picture of your pool!
