Geometry in the Real World Welcome to the natatorium! By Sarah Musselman Block 1
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!
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.
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.
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.
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.
Perpendicular lines are lines that intersect at 90 degrees.
Perpendicular lines at a natatorium are the lines at the bottom of the pool.
Parallel lines are lines in the same plane that do not intersect.
Parallel lines in a natatorium would be the tower diving boards!
A triangle is a tree-sided polygon.
A triangle in a natatorium would be the flags going across the pool.
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.
A pentagon is a five sided polygon.
A pentagon in a natatorium would be the paddles used for training lifeguards.
A hexagon is a six-sided polygon.
An example would be the weights that the divers use in the weight room at the natatorium.
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.
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!
A trapezoid is a quadrilateral with exactly one pair of parallel sides!
A trapezoid at the natatorium would be the speakers.
A parallelogram is a quadrilateral with two pairs of parallel sides.
An example would be the railing of the stairs at the natatorium!
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!
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!
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!
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!
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!
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!
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!
