This document defines and provides examples of basic geometric shapes including points, lines, planes, angles, triangles, quadrilaterals, circles, spheres, cones, cubes and pyramids. Key properties are described, such as a point having no size, a line having two endpoints, a plane extending forever, and types of triangles and quadrilaterals being distinguished by their angles or parallel sides. Examples are given for applied uses of shapes like circles in buttons or trapezoids in storage boxes.

1. Real World Geometry Jasmon Haggerty 2nd Block

2. Point An undefined term in geometry, it names a location and has no size

3. Line (Segment) A line with two endpoints

4. Plane It is a flat surface that has no thickness and extends forever.

5. Angle A figure formed by two rays with a common endpoint.

6. Perpendicular Lines Lines that intersect at 90° angles.

7. Parallel lines Lines in the same plane that do not intersect.

8. Triangle A three-sided ploygon

9. Right Triangle A triangle with one right angle

10. Pentagon A five sided polygon

11. Hexagon A six-sided polygon (a soccer net)

12. Square A quadrilateral with four congruent sides and four right angles

13. Rectangle A quadrilateral with four right angles

14. Trapezoid A quadrilateral with exactly one pair of parallel sides (Trapezoid box)

15. Parallelogram A quadrilateral with two pairs of parallel sides. A part of a door

16. Circle The set of all points in a plane that are fixed distance from a given point called a center of a circle. A button

17. cylinder A three-dimensional figure with two parallel congruent circular bases and a curved later surface that connects the bases.

18. Sphere The set of points in space that are a fixed distance from a given point called the center of the sphere.

19. Cone A three-dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex.

20. Cube A prism with six square faces.

21. Pyramid A polyhedron formed by a polygonal base and triangular lateral faces that meet at a common vertex.
