Non-congruent alternate interior angles

This is a house. This object shows non congruent interior angles. The pink line extends down and that forms alternate interior angles that are not congruent with the green line, because one line is obtuse and one angle is acute. In the real world a house is used by people. Houses are found in neighborhoods. This is in the advertisement industry. http://www.google.com/imgres?um=1&hl=en&client=safari&tbo=d&rls=en&biw=1192&bih=639&tbm=isch&tbnid=mmR7VAMB91MUYM:&imgrefurl=http://www.nps.gov/glca/historyculture/navajobridge.htm&docid=kURt39YRODgTsM&imgurl=http://www.nps.gov/glca/historyculture/images/Navajo_Bridges_1.gif&w=556&h=417&ei=_jWgUIa_Da2G0QGxsYHwCw&zoom=1&iact=rc&dur=358&sig=101161591993119626923&page=1&tbnh=146&tbnw=191&start=0&ndsp=18&ved=1t:429,r:6,s:0,i:169&tx=51&ty=63

Supplementary angles that are not a linear pair

This is a field goal. These are found on sports fields. They are used by football players. These two angles are supplementary but they are not a linear pair. The two right angles in the corners are supplementary(they equal 180) but they are not a linear pair. http://www.google.com/imgres?um=1&hl=en&client=safari&tbo=d&rls=en&biw=1192&bih=639&tbm=isch&tbnid=qNSmk8Wt5v4sFM:&imgrefurl=http://thoughtupload.blogspot.com/2012/09/red-zone-field-goals-reacting-to-fixing.html&docid=IUsHW8GlzJgqLM&imgurl=https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjGHzXwws5Qgc3Q_nVW-6kMxLBHVE4J-oNmKB4K4d1di1Ux031hQ-LbqLi9Jo6x5dYDWbpUFihrxjTZ0UrN6Mpsp_d8VtMTpB3BQGjdeC7_3A-u_G7jT5bwISoULSEH9pM_3YMpUX75ppVy/s1600/FieldGoal.jpg&w=1280&h=853&ei=SDOgUOv6KavE0AGLt4GwCw&zoom=1&iact=rc&dur=331&sig=101161591993119626923&page=1&tbnh=153&tbnw=230&start=0&ndsp=13&ved=1t:429,r:0,s:0,i:144&tx=87&ty=32

Adjacent non-supplementary angles

This is a picture of a tripod. This object shows adjacent non-supplementary angles because the angles are adjacent and they are not supplementary. I took this picture. This object can be found in many places, inside and outside. Tripods are used to keep a camera or binoculars steady when someone is not holding it. This industry is metal fabrication.

Skew Lines

This is a coffee table and the blue lines shown above form skew lines. Skew lines never intersect but aren't parallel. This object was found in a magazine but in the real world coffee tables are used as decoration and they are also used as a place to set things. This is found in the marketing/adverting industry because it is a picture in a magazine. I took this picture. 

Segment bisector

This is a mullion. The segment is highlighted in pink and the bisector is blue. The blue lines bisects teh pink line, which makes it a segment bisector. It also creates 4 right angles and is congruent.This object was found in my house. Mullions go across windows to divide them into equal sections. They are also used as decoration. This is from the marketing industry. Mullions are used in nice houses and if a realtor wanted to sell a house they might show the customers the mullion. I took this picture.

Vertical Angles

This is a picture of floor tiles. Their angles create vertical angles and they are all congruent because they are formed by the same lines at the same angles. For example, 1 and 3 are vertical angles and 4 and 2 are vertical angles. This object was found in my kitchen, but tiles can be found in many places. In the real world tiles are used as a from of flooring, wall coverings, or counter coverings. They can be found outside and inside. In the real world carpenters use them and any person who walks on them uses them. I took this picture. 

Angle Bisector

This is a window frame. The angle is highlighted in purple and the bisector is yellow. The bisector is the middle of the angle. The window frame was found inside my house. In the real world a carpenter uses this because they frame the windows. Window frames are used to decorate windows. I took this picture.
