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