Vertical Angles

This trim contains two vertical angles. There vertical angles because the two angles form a linear pair with the same angle. The trim is important because they keep the ceiling together. Without the trim the ceiling would fall apart. Trim is found all over Severn's walls and keep the ceilings in place. I took this picture on my Iphone in the mac lab.

Congruent Acute Angles

The ribbon is containing two congruent angles. These angles are acute because they are less than ninety degrees. The red symbol at the bottom shows the two angles are equal to each other. Ribbons are a long, narrow strip of fabric, used especially for tying something. Ribbons are used to hold up things like papers, artwork, and pictures. Many professions use ribbons such as fashion designers, interior designers, and artists. I took this picture on my iPhone in Mr. Witzel's room.

Angle Bisector

The kiwi in this picture represents an angle bisector. The seeds (outlined in blue) represent the angle. The black line in the center of the seeds is the bisector. The bisector splits the kiwi into two equal parts. Kiwis are a delicious fruit that can be found in every grocery store and used in restaurants. You can eat kiwis plain or they can be found in smoothies and lots of desserts.

Skew Lines

This desk contains skew lines (outlined in blue) because the two lines are nonparallel in space and don't intersect. Desks are a piece of furniture with a flat or sloped surface and typically with drawers, at which one can read, write, or do other work. Desk are mainly used in office buildings and are a great way for people to have their own personal space to do their work. I took this image on my Iphone at my house.

Segment Bisector

This midfield line of this soccer field is an example of a segment bisector. The midfield line is a segment bisector because the line divides the soccer field into two equal parts. Soccer fields are fields that people play soccer on. These fields are used primarily used for soccer but can also be used for other sports such as, football, lacrosse, and field hockey.

Three or more coplanar parallel lines

These blinds show three or more coplanar parallel lines. Parallel lines are lines that do not intersect. Coplanar means to be in the same plane. The lines in purple are all parallel to each other and are contained in one plane. Blinds are a window covering and made out slats of fabric, wood, plastic or metal. Blinds are used on windows in almost all houses and buildings. I took this on my Iphone in the library lab.

Line Perpendicular to a plane

This picture of an oil rig represents a line perpendicular to a plane. The platform is the plane and the perpendicular line is the drill (circled in green). This line is perpendicular to a plane because the line is perpendicular to every line it intersects. This oil rig is used  to drill and then produce oil and natural gas in the ocean. The oil is used in Transportation Fuels (Gasoline, Diesel, Jet Fuel), Asphalt, Fertilizer, Heating, Feedstock, and Plastics.

Supplementary Angles that are not a linear pair

The picture of these musicians contain a pair of non linear supplementary angles. The angle outlined in green equals 150 degrees and the angle outlined in purple equals 30 degrees. The sum of these two angles add up to 180 degrees, forming a supplementary angle. This picture is of a woman playing a flute. Flutes are musical instruments of the woodwind family. Flutes can be found in orchestras, and concerts. Many people also play the flute for enjoyment. I found this image at: http://www.vagabondjourney.com/2009-1/09-3184-musicians-metro.JPG

Adjacent non-supplementary angles

This picture of an oil pump contains adjacent non supplementary angles (outlined in purple). If the two angles were supplementary then they would have to equal 180 degrees, which these angles do not. They are adjacent because they have a common vertex. If these two angles were adjacent supplementary angles their non-shared sides would form a straight line. Oil pumps are pumps that keeps a supply of oil on moving parts. The oil is then used for things like gasoline,solvents, and electrical generation.

Non-congruent alternate interior angles

These noodles are an example of a non-congruent alternate interior angle. Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the two lines. Angle 1 and 2 (outlined in green) are not congruent because there on opposite side of each other. If they were on the same side they would be congruent. Noodles are dough made of wheat, flour, and water that are molded into a variety of shapes and boiled. Noodles are made in households and restaurants all around the world.
