Segment Bisector

Photograph by: Cece

This image is a picture of a portion of my Severn coat. It keeps me warm in the winter time as well as at school. The compass on my coat has a segment bisector in it. A segment bisector is a point, ray, line, segment that intersects a segment at its midpoint. The segment being bisected in this picture is blue and it is being bisected by the green segment. The turquoise tick marks represent equal sides to show that the green segment actually bisects the blue segment. 

Skew Lines

This is a picture of a camera used for broadcasting. These kinds of cameras film things that we see on TV like: sports, contests, news shows, and political events. These cameras are used by the broadcasting industry and TV networks all the time because this is how they get their information that they show the world on TV. The purple lines highlighted on the camera are an example of skew lines. Skew lines are lines that don't intersect and aren't on the same plane. The lines highlighted on the camera will never intersect because they both go on horizontally for ever and the are not on the same plane because the line on the handle is in front of the line on the camera itself.

Supplementary Angles that are Not a Linear Pair

This is a picture of a microphone used in a recording studio. Microphones are used by the music production industry to record sound, usually of people's voices signing. Musicians use microphones to record their voices as well as amplify their voices. The blue highlighted portions of this picture represent angles in the microphone and stand. These angles are right angles, as shown in orange, and they do not touch, so they are not adjacent. Two right angles adds up to 180 degrees, which fulfills the definition of supplementary angles. These angles are not a linear pair because they don't touch even though they are supplementary.

Adjancent Non-Supplementary Angles

This is a image is a picture of the the Pyramid in the Louvre looking up  from inside the visitor center in the Louvre. This picture was taken in March 2012 in the Louvre, Paris, France. Adjacent non-supplementary are angles that have a common vertex and side, but don't add up to 180 degrees. The red angle in this picture shares a side and vertex with the purple angle. Even though the angles appear to make a line, they actually don't form a straight line. This pyramid is used to look pretty for photographers, be a roof for the visitor center, and to draw even more attention to the world-famous museum.

Angle Bisector

This image is of measuring spoons that is used in the kitchen. The angle is highlighted in green, and it is bisected by the blue line. Bisecting is when a line or ray cuts an angle in half. An angle bisectors is a ray that divides an angle into two angles. Measuring spoons are used in the food industry to measure ingredients out for recipes. Chefs,both professional and not, use measuring spoons to measure ingredients to make delicious food. 

Line Perpendicular to a Plane

This is an image of golfer putting on a green during a practice round of the US Open in 2011. The flag stick, which is highlighted in purple, is part of a line that is perpendicular to the plane of the green, which is outlined in red. A perpendicular line is a line that intersects with another geometric object to form a right angle. The right angle in this image is shown in blue. This image could be used by the marketing/advertising industry to advertise the US Open or the golfer in the image. Callaway Golf could use this image for advertising because the golfer is sponsored by them as well as Adidas.

Parallel Lines in the Same Plane

This is a picture of harpoons in storage. This picture was taken in Montauk, New York in 2007. The harpoons were used for whaling and the whalers used the blubber to make oil. This oil was used for lamps that were used by the hospitality industry among others. These lamps were used instead of electric lights in hotels and restaurants, as well as ordinary people's homes and business offices. The red lines drawn on the image are parallel lines, which means that they will never intersect. The blue box drawn in the picture represents the plane that all three of the lines go through. These lines are coplanar because they all lie  in the same plane.
