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.
