Adjacent Non-Supplementary Angles

This is a picture of pieces of pizza making adjacent non-supplementary angles. I found the picture on http://myworldreviews.com/reviews/Lugano_2_For_1_Pizza-181/figurebig-608.jpg. This is part of the food industry. Adjacent angles are used in blue prints for making buildings.

Transversal

This transversal is a picture of Manhattan. I got this picture on http://excitingny.com/images/manhattanmap.jpg. This is an industry of transportation. Obviously transversals are used for road mapping. Also they are used in blue prints.

Supplementary Angles That are not a Linear Pair

This photo is a picture of the Leaning Tower of Pisa in Italy. The red lines in this picture demonstrate adjacent non-supplementary angles. I found this picture on http://intermath.coe.uga.edu/dictnary/images/angles/supang1.jpg. Adjacent non-supplementary angles are used a lot for street corners.

Segment Bisector

This is a photo of a segment bisector. I took this picture at my house of the window and cropped it so it would be easier to tell what the bisector was (security). This is a segment bisector because the horizontal line bisects the segment of the two vertical lines

Vertical Angles

I took this picture on my bathroom floor. This is an example of vertical angles because the two lines are making two equal angles. Vertical angles are s

Skew Lines

I took this picture of my speaker doc in my room (music production). The red lines drawn on the doc are skew lines because skew lines are lines that don't intersect and are not parallel. Skew lines are used a lot in everyday because skew lines are basically any lines that aren't connected so any lines that aren't connected and aren't parallel are skew lines.

Angle Bisector

This is an angle bisector. I took this picture in Mr. Beckman's room, it is a picture of a window and the blind string is bisecting it. (For some reason the picture won't rotate. Sorry!)  An angle bisector is used in things like clocks for example, because the hand for the seconds bisects the minute and hour hand. Also, bisectors are used in making kite patterns.

Line Perpendicular to a Plane

This object is an intersection sign at a road. The intersection sign is perpendicular to the plane it is on. I found this object on http://ww2.valdosta.edu/~dkrabel/perpendicular.jpg. As you can see, perpendicular lines are commonly used for intersections. Also they are used on windows a lot to separate them.

Congruent Angles

This is a picture I took in the mac lab of the corner of the desk. The desk shows congruent angles because the angle is a right angle. Congruent angles are used in everyday life things such as stairs, houses, televisions, etc.

Coplanar Parallel Lines



This is a picture I took of three or more coplanar parallel lines. This object exhibits parallel lines because the pictures are distributed evenly along the wall. The pictures on the wall were found in the computer lab in the library. There are many real world examples like road lines. If the lines on the road were not parallel, it would be much harder to drive without getting into crashes. Also the beams of houses are parallel so that the house will be sturdy.
