Two non congruent alternate interior angles

The angles 1 and 2 are non congruent alternate interior angles because the blue lines are not parrallel and angle 2 is a right angle and angle 1 is not. They are alternate interior because outside each blue line would be considered exterior. I took this picture and I used pencils as the angles. Pencils can be found in any school, store, or work environment. Students, teachers, designers, artists, and many more workers use pencils everyday. 

Segment bisector

The green line represents a segment and the blue line is bisecting that segment. We know this because the pink tic marks mean that both side are congruent. This is a picture of the Swiss flag. Flags are an important part of each country. I found this image at http://www.united-states-flag.com/world-switzerland.html

Supplementary angles that are not a linear pair

These angles are supplementary but don't form a linear pair. A linear pair is when two supplementary angles are adjacent formed by two intersecting lines. These two are not adjacent because they don't shar a common side or vertex. The keyboard was a good example because we use it everyday and everyone who has any electronic device will most likely be using a keyboard at some point in time. I took this screen shot of my ipad. 

Adjacent non-supplementary angles

The red lines represent an adjacent non-supplementary angle. It isn't supplementary because the two angles don't form a line and they are adjacent because one side is shared and they have the same vertex. Clocks are an everyday use and I usually check the clock more than once for each class. We can also use clocks to find angle measures in geometry class.

Skew Lines

The blue line and the orange line represent skewed lines. Skew lines are lines that never intersect but aren't parrallel so they are on different planes. The street sign makes a perfect example because each sign is like a plane so the orange and blue will never meet. Street signs are very helpful in this world because when driving they let us know our location. Street signs are generally located at inserctions but can be anywhere.

Angle bisectors

This maple leaf has lines on it that form different angles and the blue lines represent the angle while the white line is the angle bisector. An angle bisector splits the angle in to two congruent parts. This can work on any angle no matter the degree. Maple leafs grow on trees and can be produced for maple syrup. This leaf is in its fall state because the color is red, they can also be green. I found this photo online: http://en.wikipedia.org/wiki/File:Canadian_maple_leaf.jpg 

Three coplanar parallel lines

The pink lines are parrallel coplanar lines because they are on the same plane and will never intersect. Blinds are very useful because they let light into one's house, instead of using electricity. The lines will still be parrallel and coplanar if the blinds are opened. Blinds are a everyday use to keep light out or let it in, almost every home has blinds installed for privacy. I took this photo in my house with my phone.
