This document discusses how various geometric shapes and concepts appear in different sports. It provides definitions and examples of points, lines, planes, angles, perpendicular and parallel lines, triangles, right triangles, polygons like pentagons and hexagons, quadrilaterals like squares, rectangles, trapezoids and parallelograms, circles, cylinders, spheres, pyramids, cones, and cubes. Examples are given for each shape showing how it relates to elements found in sports like baseball, swimming, soccer, basketball, track, skateboarding, diving, tennis, cheerleading, hockey, nascar and billiards.

13. RectangleDefinitionRectangle- A quadrilateral with four right angles.Diving BoardIn diving, a diving board is a rectangular shaped quadrilateral with four right angles.

14. TrapezoidDefinitionTrapezoid- A quadrilateral with exactly one pair of parallel sides.Soccer GoalIn soccer, a soccer goal is shaped like a trapezoid and has exactly one pair of parallel sides.

15. ParallelogramDefinitionParallelogram- A quadrilateral with two pairs of parallel sides.Track HurdleIn track, a hurdle is a quadrilateral with exactly two pairs of parallel sides.

16. CircleDefinitionCircle- The set of points in a plane that are a fixed distance from a given point called the center of the circle.Nascar TireIn nascar, a tire is in the shape of a circle.

17. CylinderDefinitionCylinder- A three dimensional figure with two parallel congruent circular bases and a curved lateral surface that connects the bases.Baseball BatIn baseball, a bat is a three dimensional figure with two parallel congruent circular bases.

18. SphereDefinitionSphere- The set of points in space that are a fixed distance from a given point called the center of the sphere.Tennis BallIn tennis, a tennis ball is a spherical shaped object.

19. PyramidDefinitionPyramid- A polyhedron formed by a polygonal base and triangular lateral faces that meet at a common vertex.Cheerleader PyramidIn cheerleading, a pyramid is formed by several cheerleaders stacked on top of one another.

20. ConeDefinitionCone- A three-dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex.Cheerleading ConeIn cheerleading, the cone they use to project their voices has a curved lateral surface that connects the base to the vertex.

21. CubeDefinitionCube- A prism with six square faces. All-Around Scoreboard In some sports like hockey and basketball, there is an all-around scoreboard that is a prism with six square faces.
