This image is the FedEx Symbol. This signifies an angle bisector because when you look at the arrow formed by the E and X, note that it forms the arrow. In the arrow, the arrow head forms an angle and the arrow tail shows a bisector. There fore an angle bisector is shown. This object or sign was found on the internet. This sign is used on FedEx trucks and airplanes when they are transporting mail. Otherwise it is used for commercial purposes.

Three or more coplanar parallel lines

C:\Users\Arjun\Downloads\lunapic_135060190984424_17.gif

This is a photo of blinds. These blinds demonstrate coplanar parallel lines because they lie in the same medium or plane and they will never touch. This is the definition of coplanar parallel lines. I took this photo of my blinds from my phone. Blinds are used to give privacy or security to those who are inside a house. It is used by many people around the world.

Congruent Acute Angles

This is a picture of a fan. This picture shows Congruent Acute angles. It may not appear so (due to my shift of hand during the tracing of lines) but they had the exact same angle and size. This object was found off the internet. It is used in houses every day to cool off people. This system also functions off electricity or oil.

Skew Lines

The image shown here is a cabinet. It shows skew lines because these lines will never intersect and are not on the same plane. That is the definition of skew lines. This picture was taken off my phone right next to my desk.This object is used by almost everyone in the world who has books. It is used to store books, notebooks, papers, folders, and research.

Adjacent Non-Supplementary Angles

C:\Users\Arjun\Downloads\lunapic_135069230734497_5.gif

This image is a picture of a Clock. It also serves as an example of Adjacent Non-Supplementary Angles. The minute and hour hand show an obtuse angle, and the hour and second hand show a acute angle. This object was found in the school library and taken off my phone. It shows time and is also made from metal. Therefore it is part of a metal fabrication industry.

A line perpendicular to a plane

C:\Users\Arjun\Downloads\lunapic_135069230734497_7.gif

This is a image of a smart board. It is also a example of a line perpendicular to a plane. As seen in this picture, the pen held against the plane, demonstrates a line coming directly out of the smart board, forming a perpendicular line. This smart board was found in Ms. Palmer's room in Creeden Hall and was taken off my phone. Smart boards are often used to take notes, solve problems, and teach lessons. This is used in the information technology field and is found in many classrooms.

Supplementary angles that are not a linear pair

C:\Users\Arjun\Downloads\lunapic_135069230734497_12.gif

This is a picture of a keyboard. It is also an example of supplementary angles that are not a linear pair. This is shown because these angles form a straight line but are not touching therefore they are not a linear pair but they are supplementary. Keyboards are used with every computer (at least i hope so) to type up papers, notes, projects, ect... This keyboard can be found in the library and was taken off my phone. Keyboards are used and manufactured in the information technology industry as well.
