Composite Solids

This is a pier pole found in my beach house neighborhood in Ocean City. Maryland. The pole itself is to help support the pier, along with all the other poles. The white thing at the top could be for decoration, safety, or so one knows where the pier is if they are walking on it late at night. The white thing at the top is a cone figure, which is connected to the cylindrical pole, creating the geometric idea of a composite solid. Pier poles are used to support the pier, which keeps objects and people above the water. They are also used to tie boats, crab cages, and other water-related things off of. The pier makes them (boats, cages, etc.) easy to get to, and not getting wet by the river/sea water in the process.

Regular Polygon With More Than or Equal to Five Sides

What is pictured here is an air conditioning/heat filter located in the Legard Learning Village on the Severn School campus. Creating the actual geometric shape is the protecter for the filter, letting only small particles enter the boundary, keeping large objects like humans and debris out of the filter. The shape created by the filter protector is a regular hexagon: a polygon with six congruent sides and angles. Air conditioners and heaters are used in almost every building, including trailers (called "learning cottages" by the Severn School community). In order to ensure clean air is given by the air conditioner/heater, a specific type of filter must be used to filter out the bad stuff that humans don't need, or could even be potentially dangerous. This specific filter happens to be on the outside of the building, but they may be located inside or outside of whatever building it is providing heat for. 

Supplementary Angles that are not a Linear Pair

Supplementary angles are two angles whose degrees add up to 180 degrees. A linear pair is formed when two angles are adjacent and their non common sides are opposite rays. In this picture, two non adjacent 90 degree angles are formed, thus creating supplementary angles, yet not a linear pair. 

Square linoleum floor tiles are shown. Squares are geometric figures: a polygon with four congruet sides and angles. Also, many lines are in this picture, which are what forms the angles. Only 180 degree and 90 degree angles are created by the floor tiles and their lines.

These floor tiles were found in our very own Doctor Martin's biology classroom on the second floor of Creeden. Tiles can come in many different shapes, forms, and colors. One use is for flooring and/or wall designs in rooms such as bathrooms and kitchens.

Non-Congruent Alternate Interior Angles

In this picture, my suitcase was in a plastic bag held together by tape. This was because my suitcase somehow broke, and instead of having a handel, there was a giant hole in the top. So, in order to keep all of my clothes together, the suitcase was wrapped in plastic bags, which were then secured by tape. This traumatic incident occured in Nassau, Bahamas during this past spring break at the airport.

In the picture, there is one visible line of tape wrapped around horizontally, and one and a half visible lines of tape wrapped around vertically. The one horizontal line of tape is the transversal, while the other two are the lines that the angles correspond with. The green line, the first of the two, goes through the transversal at an angle where the interior angle to the left of the transversal equals 89 degrees. The second line (represented as the color red) goes through the transversal at an angle where the interior angle to the right of the transversal equals 91 degrees. Since 89 degrees is not equal to 91 degrees, this is a great example of non-contuent alternate interior angles.

Tape, plastic bags, and suitcases are all very useful in the real world. Tape can be used for painting, crafts, holding things together, and for sports injuries. Plastic bags can be used to hold things, for storage, or to keep things inside the bag that need to be inside or keep things out of the bag that are not supposed to be inside the bag. Lastly, suitcases are mainly used for storing clothes and other things on plane rides while going to and from a vacation, but can also be used for general storage.

Skew Lines

This is a picture of the inside of the Navy-Marine Corps Memorial Stadium during one of the Navy football games. This picture relates quite a lot to geometry because of the set up of the stadium (and many stadiums in general). The field is divided by yards with a total of 100 yards in a large rectangle. A rectangle is a geometric shape. The seating areas also are divded into sections so that the exact number of chairs fit in the amount of area. In this picture,  touchdown zone is divided into many yellow and blue squares, so the people that made the field needed to know the side of the zone they were sllowed to put the squares in, the size of the squares they were going to put in the zone, and the amount of squares that would be put into the zone(s) in total. As for the stadium lights, they need to be put in the exact right spots so that they illuminate the entire stadium, not missing a single part.

This stadium can be found in Annapolis, Maryland right outside of Downtown Annapolis. Football is a popular American sport played in almost every state, therefore many football fields/stadiums had to be made using some of these tactics: 100 yards in the correct sized football field/rectangle, designs in touchdown zones, bleachers/stadium seating, and stadium lights.

Congruent Isosceles Triangles

These objects are trianglular windows. I decided to choose the pairs of triangles as one big triangle, not the individual triangles. Triangles are goemetric shapes. The triangles I've chosen are congruent. Because of the angle that the picture was taken, the triangles do not look congruent, but they are. The two bottom angles of one of triangles are congruent, and the second triangle's angles are also congruent to each other, and are also congruent to the angles in the other triangle. The opposite sides of each of the angles are congruent to each other, and are also congruent to the same sides of the other triangle.

These windows were found at Liberty Ski Resort in Pennsylvania. Some examples of how windows are used are to let sunlight inside buildings or rooms, letting fresh air go from outside into a building or room, and getting things from one place to another.
