Vertical angles

These lacrosse sticks cross at one point and are showing vertical angles. Each of the angles that are opposite of each other are congruent because all vertical  angles are congruent. Lacrosse sticks are used to play lacrosse, which is a sport that using these sticks to catch the ball with. Lacrosse is a common sport around the world.  Lacrosse sticks are used by proffesional lacrosse players.This picture was found online:http://www.cs.trinity.edu/~rnewson/sports.htm

Line Perpendicular to a Plane

This a picture of a arm that is perpendicular to a plane(wall). Showing that the arm is perpendicular to the wall, I drew a box which shows its a right angle in the crease of the wall and the arm. Walls are mainly found everywhere on buildings and used for keeping buildings up. Arms are on mostly everyone and they are use to pick up things, writings and etc. I took this picture with my phone.

Segment Bisector

The highlighted yellow line in the middle of the window in a segemt bisector. It is a segement bisector because it interesects the purple line at its midpoint. The picture I used to show a segemtn bisector was a window. Windows are used for looking throurgh them and seeing on the other side. Windows are used by the everyday working , like police officers, firefighters, and etc.

Skew lines

This is a calculator that contains a pair of skew lines. The skew lines are at the top of the calculator and at the bottom. The two lines will never instersect and are not parallel to each other.Calculators are used to solve math problems (and sometimes a secret messages or two). Calculators are used my engineers, architects, accountants and etc. You can find calculators in the store or in most schools. this picture was found online:http://www.confluencedigital.com/resources/customer-lifetime-value-calculator/

Three or more coplanar parallel lines

 

The wall that is highlighted in yellow is plane and the pictures on the wall, that have lines on them are the parallel lines. This wall has more than three coplanar parallel lines on them. The red lins are paprellel and the blue lines are parallel with each other. The pictures are found mostly everywhere. Pictures can be taken with cameras. Alot of people use pictures for art work and showing it in their galleries.pictures are also used to express feelings. I took this picture with my phone.

Congruent acute or obture angles

 

This is a plant holder that is in the shape of a upside down trapezoid. This picture is showing congruent acute and obtuse angles. The top two angles are acute and the botton two angles are obtuse.  The obtuse angles are congruent and the acute angles are congruent. Planet holders are used my humans who want plants in there house or florist. I took this picture on my phone.

Supplementary angles that are not linear pairs

 

This is a picture of a brick fireplace. This picture is so supplementary angles that are not connected so they are not linear pairs. These angles are both right angles so they both equal 90 degrees. 90 + 90 =180 degrees. The two angles are supplementary because they equal 180 degrees. This picture was took with my phone in my house. Bricks are found everywhere. They are used to build houses, factroies, and etc.

Angle Bisector

This is a square pizza box. This pizza box is showing an angle bisector. An angle bisector is an line that divides the angle in half. Pizza boxes are used my pizza workers that deliver the pizza. Pizza box holds pizza and is used for pizza, projects, and etc. I found this picture online:http://tailgatereview.com/2010/08/30/welcome-to-papa-johns-stadium/

Adjacent non supplementary angles

This is a oven. This oven is showing adjacent non supplementary angles. Adjacent angles are angles that share a common side. the middle line is the line that the angles share. The oven is used for cooking. Chefs and the ordinary people use ovens to cook food. I took this picture with my phone.

Non-congruent alternate interior angles

 

This is a blood pressure monitor. The blood pressure monitor has mutiples angles is the cirlce. The blood pressure monitoris showing the non congruent alternate interior angles. The green lines show the non congruent alternate angles.This object is used to measure blood prassure. Most doctors use it to make sure people dont have high blood pressure.
