2. Point<br />Point- It names a specific location and has no size<br />This is a nail hammered into a wall in the garage <br />2<br />
3. Line (segment)<br />Line segment- A straight path that has<br /> no thickness and extends forever<br />This is a picture of a highway road stripe<br />3<br />
4. Plane <br />Plane- Flat surface that has<br /> no thickness and extends forever<br />This is a football field enzone and the surface of the field is a plane<br />4<br />
5. Angle <br />Angle- A figure formed by two rays with a common endpoint<br />This is a door frame that forms a 90 degree angle<br />5<br />
6. Perpendicular lines<br />Perpendicular lines- Intersecting lines that form 90 degree angles<br />The bars on this fence form 90 degree angles to one another<br />6<br />
7. Parallel Lines<br />Parallel lines- Lines in the same plane that don’t intersect<br />These tube rails on a road bridge are parallel to each other<br />7<br />
8. Triangle <br />Triangle- A three sided polygon<br />This is a TV tray and the legs form a<br />Triangle.<br />8<br />
9. Right Triangle<br />Right Triangle- A triangle with one 90 degree angle<br />This is a power pole and the <br />Wire, brace, and pole make up a right triangle <br />9<br />
10. Pentagon<br />Polygon- A five sided polygon<br />This is a crosswalk sign that forms a Pentagon<br />10<br />
11. Hexagon<br />Hexagon- A six sided polygon<br />These are hexagon shaped pavestones<br />11<br />
12. Square<br />Square- Quadrilateral with four congruent sides and four right angles<br />This is a Road work sign that is a square<br />12<br />
13. Rectangle<br />Rectangle- A quadrilateral with four right angles<br />This is a street sign that forms a rectangle<br />13<br />
14. Trapezoid<br />Trapezoid- A quadrilateral with exactly one pare of parallel sides<br />This is a bank sign that is a trapezoid<br />14<br />
15. Parallelogram<br />Parallelogram- A quadrilateral with two pairs of parallel sides<br />This is the Arby’s logo and it forms a parallelogram <br />15<br />
16. Circle<br />The set of points that are in a plane that are a fixed distance from a given point<br />This is a big clock on a tower that forms a circle<br />16<br />
17. Cylinder<br />Cylinder- A three dimensional figure with Two parallel congruent circular bases and a curved lateral surface that connects the bases <br />This is a transformer on a power pole that makes a cylinder <br />17<br />
18. Sphere<br />Sphere- The set of all points in space that are fixed distance from a given point <br />This is a sphere shaped light bulb cover<br />18<br />
19. Octagon<br />Octagon- An eight sided polygon<br />This is a stop sign that forms a octagon<br />19<br />
20. Cone<br />Cone- A three dimensional figure with a circular base and a curved lateral surface that connects the base to a point called the vertex<br />This is the top of a lava lamp that forms a cone<br />20<br />
21. Cube<br />Cube- A prism with six square faces<br />This is a Rubik cube that forms a cube<br />21<br />
