Point </p> <ul><li>Undefined term in geometry, it defines a location that has no size </li></ul> <p> 3. Line (Segment) </p> <ul><li>The part of a line consisting of two points and all the points in between </li></ul> <p> 4. Plane </p> <ul><li>Flat surface that has no thickness and extends forever </li></ul> <p> 5. Angles </p> <ul><li>A figure formed by two rays with a common endpoint</li></ul> <p> 6. Perpendicular Lines </p> <ul><li>Lines that intersect at 90 degrees angles. </li></ul> <p> 7. Parallel Lines </p> <ul><li>Lines that lie in the same plane, and are the same distance apart over their entire length . </li></ul> <p> 8. Triangle </p> <ul><li>A Three Sided Polygon. </li></ul> <p> 9. Right Triangle </p> <ul><li>A triangle with one right angle </li></ul> <p> 10. Pentagon </p> <ul><li>A five-sided polygon </li></ul> <p> 11. Hexagon </p> <ul><li>A Six-Sided Polygon </li></ul> <p> 12. Square </p> <ul><li>A quadrilateral with four congruent sides and four right angles </li></ul> <p> 13. Rectangle </p> <ul><li>A quadrilateral with four right angles </li></ul> <p> 14. Trapezoid </p> <ul><li>A quadrilateral with exactly one pair of parallel sides </li></ul> <p> 15. Parallelogram </p> <ul><li>A quadrilateral with two pairs of parallel sides </li></ul> <p> 16. Circle A circle isA line forming a closed loop, every point on which is a fixed distance from a center point. 17. Cylinders A three-dimensional figure with two parallel congruent circular bases and a curved lateral surface that connect 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. Dodecagon</p> <ul><li>12 sided polygon. </li></ul> <p> 20. Arc </p> <ul><li>portion of thecircumferenceof a circle</li></ul> <p> 21. Cone </p> <ul><li>Three dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex. </li></ul>
