Non congruent alternate interior angles

This is a slide, found in most, or all playgrounds used by children around the world for fun. The ground and the slide as lines are cut by the red line or the ladder as a transversal. This forms two alternate interior angles cut by a transversal and because the lines aren't parallel to each other the alternate interior angles aren't congruent. This is a huge attraction for kids around the world, and even for adults when the slides are bigger and higher. This picture is from a website :

Segment Bisector

This is a couch, or what some people call a love seat. This picture is taken by me in the sun porch of my house. This couch has a bar supporting the pillows and the a bar bisecting that support bar, that Bisector is in green and goes to the ground. This bar that bisects is a segment Bisector of the red segment in the picture, cutting it in half. Couches are found around the world in households everywhere as a sitting place, a comfortable seat, and even as a sleeping place in some homes. 

Skew lines

This is a painting easel, painting easels are used by artists every. To draw, paint, sketch, or what every else they can do on a piece of paper, they can also be used to display art. This picture was taken by me at Severn School in Ms. Carsley's room. Easels are used around the world by artists to create their art and display it.  This easels top and its bottom support bars create skew lines with the bottom bar being a little tilted upwards,making two lines that don't intersect but aren't parallel.

Supplementary Angles that aren't a linear pair

This is a window or window sill and it forms to supplementary angles that aren't adjacent or aren't a linear pair. This picture is taken by me in Severn School, Ms.Sotoropolis's room. Windows are found in about every house in the world and are also found in office buildings, and other buildings usually. Windows are used for not to many things, they are used for a view outside, to air out the house, and to cool the house before or without air conditioning. 

Adjacent non supplementary angles

This is a clock. This clock's hands at this specific time form adjacent non supplementary angles. This picture was taken by me in the master bedroom of my house. Clocks are used all around the world and have been around for thousands of years. They are used to tell time, as alarm clocks, and sometimes even stopwatches. They also are for decoration, and watches, mobile clocks are used by so many to keep track of time on the go, and not be late for things.

Vertical Angles

This is a coffee table with a criss cross support bottom. The crossing bars form vertical angles along with other geometric figures. This picture is taken in my living room. Coffee tables are used for several things decoration like in my picture, to eat upon, to place stuff on, and even as a foot stool. These type of tables are found all around the world and are used for many different things. 

Angle Bisector

This is a laundry basket or dirty clothes bin. This picture is taken by me in the master bathroom of my house. The beams of this basket form an angle Bisector(the blue line). Laundry baskets are also used around the world in bathrooms, basements, gyms, etc. They are used to put your dirty clothes into and carry downstairs or just store till you wish to wash them. They also can be used to store other objects and or just for decoration.
