Supplementary Angles that are not a Linear Pair

Supplementary Angles that are not a Linear Pair

http://www.hayspost.com/?attachment_id=1786
This is an image of a railroad crossing sign. The geometric idea of supplementary angles that are not a linear pair because the two angles highlighted in blue are right angles, their sum is 180 which is a supplementary angle. They do not share a line so they are not linear. This object was found online. In the real world in can be found near railroads, and it is used to indicate a road and a railroad track intersection. 

 


Non-Concrugent Alternate Interior Angles

Non-Concrugent Alternate Interior Angles

This picture is of a street sign. The image properly demonstrates the geometric idea of Non-Concrugent Alternate Interior Angles because in the second picture the two alernate interior angles do not have the same measurement - they are not congruent. This objects was found in Annapolis. In the real world a street sign is used to aid people who are going places. 
 

Segment Bisector

Segment Bisector

This picture is of a leaf. The leaf represents the geometric idea of a segment bisector because in the second picture the red line evenly cuts the blue lines. A leaf can be found outdoors. In the real world leaves are found on trees, bushes, any sort of plant life really!

This image is of a billboard. The billboard properly demonstrates the idea of skew lines because the two lines shown in the second picture rest on two different planes, so they will never intersect, like skew lines. This image was found online. In real life a billboard is used in the advertising industry for market products, events, and opinions.

Adjacent Non-Supplementy Angles

Adjacent Non-Supplementary Angles

This picture is of a child's building toy. This objects relates to the idea of adjacent non-supplementary angles because the right green yellow line bar to the shadow represent one angle and the red represents the next angle. Together these angles add up to ninety degrees or less and that makes them non-supplementary, they are complementary. This object belongs to my younger brothers and was found within my household. In the real world this object is used by children and young adults to exercise the mind and entertain.

 The image above is of an ice cream cone. The lines of the cone, highlighted in black in the second image, intersect to form two vertical angles. This objects was found online, but in the real world in can be found in food industry vendors. grocery stores, and ice cream stores are just some examples of where one may find an ice cream cone.

          This image is of stain glass windows in a church. Here is an excellent demonstration of angle bisectors. As you can see in the image below, the two purple lines represent angles, and the yellow represents a lines bisecting the angle. When a line bisects an angle, if cuts it perfectly in half, or bisects it. This object was found from an online resource. In the real world this is used in the metal fabrication industry to make structures more stable and form works of art.

Congruent, Acute, or Obtuse Angles

Congruent, Acute, or Obtuse Angles
   
      These images show a set of desks and chairs in a computer lab. The pictures relate to the geometric idea of Congruent and Obtuse Angles firstly because they create two angles on each side. Secondly, they form two wide angles shown in the picture below. Lastly, they are both two angle that are also both wide - so therefore they are congruent. This picture was created by myself, I took the picture with my phone. The images in this image can be found in the Mac Lab on the second floor of Creeden at Severn School. In the real world the Mac Lab and the objects within it are used for learning and internet browsing by Severn students. These objects are considered useful in the industry of technology and information.

              

Line Perpendicular to a Plane

The image showed above is of a man standing on the beach at sunset. This picture properly displays the geometric idea of a line perpendicular to a plane because the beach or ground is a plane, and the man is like a line, perpendicular to the plane of the beach. This image was found on the internet, but if you can stand on ground you too can display this geometric idea. In the real world the image can be found if you stand on ground which would represent a plane, and you standing on the plane would act like a line. 

Coplanar Parrallel Lines

Coplanar Parallel Lines  
The image above shows a brick wall. It demonstrates the geometric idea of Coplanar Parallel Lines. The picture below shows more clearly the idea stated. A brick wall can be found in the most common of places. Places such as outside, on the exterior of a building, indoors, providing supportive yet stylish walls. This picture was found online - but one may find a brick wall by walking around in their surroundings. In the real world a brick wall is used as a wall in buildings or as a sort of short fence.
