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.
