The document defines and describes basic geometric shapes and terms including points, lines, planes, angles, triangles, quadrilaterals, circles, cylinders, spheres, cubes, pyramids and cones. It provides the formal definitions for these terms and shapes as undefined or basic terms in geometry without thickness or size limitations that extend indefinitely in some cases. The project involves taking photos of these shapes in the real world during a family trip to Austria.

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

3. Line (segment) An undefined term in geometry, a line segment is a straight path that has no thickness and stops at two given points.

4. Plane An undefined term in geometry, 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 degree angles.

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

8. Triangle A three sided polygon.

9. Right Triangle A triangle with one right angle.

10. Pentagon A five-sided polygon.

11. Hexagon A six-sided polygon.

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.

15. Parallelogram A quadrilateral with two pairs of parallel sides.

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

17. Cylinder A three- dimensional figure with two parallel congruent circular bases and a curved lateral 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. Cube A prism with six square faces.

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

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

22. About this project All of these pictures were taken in Austria this summer during a trip with my family.
