Perpendicular Lines


The line going into the ground in this picture is a perpendicular line. In the picture the ground (colored pink) is the plane, while the line (colored green) is the perpendicular line. A perpendicular line will always create a right angle when it crosses a line. This picture shows an oil pump which is used by oil miners. This image can relate back to the oil industry, which is important for daily life because oil is a main natural gas, used for running cars and other objects of use. I found this picture on the computer at Severn School.

Non-congruent Interior Angles


This picture is of the album Master of Puppets by Metallica. If you look close enough on the two top corners, multiple string are attached to the crosses. This causes alternate interior angles, yet these one are not congruent. If this is to hard to see, then for a bit of help look toward the white line, crossing the bright yellow line to form angles. The black semicircles show the angles, in this case alternate interior.
These angles are not congruent because the two white lines are not parallel. The two have already crosses at the top of the picture. This picture is the album cover of the album "Master of Puppets". This relates back to the music industry because Metallica is a hard rock/ metal band.
I found this picture on the internet.

Supplementary Angles Without a Linear Pair


This picture is of a sunrise. The lines that are veering off of the image form a supplementary angle, without a linear pair. This is because two angles are needed for a linear pair. Instead of having two lines, this sunrise has three different angles, as show by the defining lines drawn on to the image. I found this picture on the internet.

Skew Lines

This picture is of a computer keyboard. The keys on this form skew lines because they are all in the same plane (the keyboard) but the spaces in between each key don not cross. This is shown by the red, blue, and purple lines. Even though they are inside the plane of the keyboard, they do not cross or touch. Computers are used by almost everyone. In fact, this blog is being written on a computer. Computers are a part of the information technology industry, because they can be used to collect, write, copy, paste, or read information. I took this picture on my phone.

Segment Bisector

This makeup container has a segment bisector. In this picture, there is a row of different make-up containers, all containing different shades and colors. There is a line that has the names and numbers of the kind of eyeshadow This is shown by the green line, which is splitting the line between the containers evenly. This relates back to the marketing industry, because when I took the picture of this make-up, it was on display in a cosmetics store, the objective to be seen and tried (and hopefully bought). As I already said, I took this picture with my phone.

Congruent Acute/Obtuse Angles

This picture shows a bunch of sticks that have been soaked in a substance that has a serene sent. Besides smelling good, a few of these sticks are congruent acute angles. The pink lines show the the most visible lines, the closest, are congruent. This means that the angles are the same, in this case less that 90 degrees. The two lines that run across the three vertical lines are the same, showing that these angles are the same amount of degrees. I took this picture on my phone.

Angle Bisector


These three lines form an angle bisector, however they also make up the base of a coffee table. This is an angle bisector because the angle(the two outer metal poles) is split down the middle by the bisector, or in this case the third pole, that gives the table balance. This is shown by the blue lines that show the angle, and the yellow line that is the bisector. The semi-sircles show that each side is congruent, and that the angle is bisected. This picture was taken on my phone.

Adjacent Non-supplementary Angles

This picture is of non-supplementary angles (angles that are 180 degrees), but are still adjacent. This statue is of a bunch of roses, which all have different stems, but the artist put them all together to make a bouquet of sorts. The bright red lines show the adjacent angles, which means that they are next to one another. It also show that they are not supplementary, because they do not have enough lines or degrees to equal 180. This artwork was created by an artist to be shown, which is exactly what it is doing at this very moment. I took this picture on my phone.

Vertical Angles

This picture is of a jar that is on the table in my house. The checkered pattern forms vertical angles which have been outlined in purple, while the angles themselves are shown by the green and blue lines. The angles are equal because the angles themselves are vertical, and when this s the case they are always congruent. The jar has multiple vertical angles, however since the jar is a cylinder the squares get warped, so I took a picture of the ones facing me to make them as straight as possible. Most people have jars or crates of some sort, because they are good for storing items. I took this picture with my phone.

Coplanar Parallel Lines


These stitching on this pillow are coplanar lines because they are all within the same plane/square (in this case the pillow). The three horizontal lines are inside the plane, and parallel as well. A pillow can be seen as a plane due to the similar shape, while the stitching, which is inside the pillow like the coplanar lines are in the plane, and this pattern is like the lines crossing the inside of the plane. These lines are also parallel, meaning that the three horizontal lines will always stay in the same direction. If this sound confusing, it means that the red square is the plane, while the there blue lines are the coplanar parallel lines. Pillows can be found in every house, apartment, hotel, or resident home/shelter. These can be related back to the hospitality industry because people volunteering can create and then give pillows like these to people around the world.
