segment bisector

This cross shows a segment bisector because the vertical line crosses the horizontal line in the middle. As you can see in a cross the line crosses in the middle. I got my picture from this website: https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhce3gWf4pua0FaEyiTz7mfE9NjvqGrQ4J3XhvzAw0rcCr32obFE862M3izRcMqW0sSJI1bn_zwYsYaCM_Qm1nt9geTvzobVa01nqagH6mIQIc5gTCUI9RXkh-_P5qauHZRuGGP4c3gfeoC/s1600/cross2.gif

Three or more coplanar parallel lines

This is the ceiling of a room and it demonstrates three or more coplanar parallel lines because all the lines as you can see are parallel and that are all contained in the same plane. This is found on all ceilings and are used everywhere in todays society. This is an original picture taken from my Iphone.

Line perpendicular to a plane

This is a picture of a shelf and the object supporting the shelf. It shows that a line if perpendicular to a plane because the lines meet at a point. This object is found in offices and wherever you need to store things. It is used in marketing because they are trying to sell certain things. This is an original picture taken from my Iphone.

Congruent acute or obtuse angles

This is a picture of 2 pencils forming vertical angles. They form vertical angles because the angles are opposite of each other. The pencils are found in offices, schools, anywhere. It is used in any kind of industry because you need to write things down in any industry. This is an original picture taken from my Iphone.

Supplementary angles that are not a linear pair

This is a picture of a protractor and a ruler and they demonstrate supplementary angles that are not a linear pair. This is shown by the lines because it is separating it into 2 parts by the ruler. These are found most likely in a math room, so this would be a mathematician industry. The protractor is used to measure angles and the ruler is to measure length. This is an original picture taken from my Iphone.

non-congruent alternate interior angles

This is a picture of 3 dry erase markers.  They show that they are non-congruent alternate interior angles because they are on opposite sides and the angles are not the same. These objects can be found in schools or business, anywhere that has a dry erase board. It is used in the teaching industry for example by writing things on the white board for students to copy down as notes. This is an original picture taken from my Iphone.

Vertical Angles

These are scissors and they are described as a pointy tool used to cut things. This shows vertical angles because the 2 angles are on opposite sides and are equal. You can see they are vertical angles by the purple lines on the top and bottom of the scissors.

skew lines

This is a picture of a nightstand. This object shows skew lines because they will never touch. A nightstand is most commonly found beside your bed. People use them in the real world to put things on where you can easily access them if you need them. Here is where I got my picture from: http://www.ioffer.com/si/bedside+table

Adjacent non-supplementary angles

This is a clock and it is described as a round shape with numbers in it. Clocks are found everywhere you go; houses, restaurants, schools, anywhere. People use clocks to tell what time it is. These angles are adjacent and not supplementary because the angles are next to each other and do not add up to 180 degrees. This is often demonstrated by a clock, as you can see in the picture. It is used everywhere, but one example is hospitality. You have to know surgery times, and what time to give medicines, and much more.

Angle Bisector

This is a piece of pizza and it can be found in restaurants. It is used in the food industry, and people use to get energy. This angle is an angle bisector because it splits the angle into two equal angles. In the real world you would use a pizza cutter to bisect the angles.
