Three Or More Coplanar Parallel Lines In A Living Room Chair

Above is an image of a chair in my living room. My family and our cats use this chair to sit on or lay on. The chair has three coplanar parallel lines that are highlighted in the color orange. These lines are made by the edge of the cushion on the chair, the edge of the bottom support of the chair, and the cushion meeting the bottom support of the chair. These lines are all on the same plane and will never intersect if they were extended.

Line Perpendicular To A Plane In A Lamp

The above object is a lamp in my living room. My family and I use this lamp for light. There is a flat base highlighted in white that holds up a sturdy straight pole that's highlighted in maroon. The pole holds up the lamp shade and light bulbs. The pole and the base are perpendicular to each other and create ninety degree angles with each other. The pole is a line and the base is plane. This means that a line is perpendicular to a plane.

Congruent Obtuse Angles In A Rocking Chair

The above image is of a rocking chair which I use to sit on and as a decoration. This rocking chair was in my living room when I took a picture of it. It creates two pairs of congruent obtuse angles. One pair of congruent obtuse angles are highlighted in green. The other pair of obtuse angles are highlighted in white. Each pair are made from the wood being put together at different angles to hold up the chair.

Angles Bisector On A Cabinet

The object above is a cabinet made of wood in my dining room. My family uses this to store napkins and silverware in. At the corner of the cabinet, two pieces of wood are put together which create a line segment that's highlighted in yellow on the left and orange on the right. This line segment bisects angle made by the corner of the cabinet meaning that the two pieces of wood leave the corner of the cabinet at the same angle. The angle made by the corner of the cabinet is highlighted in orange on the right and yellow on the left.

Vertical Angles In A Cabinet

The object above is a cabinet in my room. I use it to organize and hold my clothes. I also, use it to put papers on top. There are six congruently shaped drawers. These create two columns and three rows. The line inbetween the two columns and and the first line separating the first two rows are highlighted by black lines. These lines create two pairs of vertical angles. One pair is highlighted in two green lines and another pair is highlighted in a blue line. 

Supplementary Angles That Aren't A Linear Pair

In the picture I took above, the object in it is a fireplace and its mantel.  My family and I use it to have fires and for decorations. The two sides of the mantel that are highlighted in purple create supplementary angles that are not a linear pair. More supplementary angles that are not a linear pair are highlight in green. These angles are made from the sides of the fireplace.

Segment Bisector

The above picture is of a closet with two doors. My family and our guests use this closet to put our coats and shoes in. The doors help to keep things tidy and put away. Each door is the same size and they fit into the door frame together. The blue line is highlighting the meeting line between the two doors. The black line highlighting the top of the door frame is bisected by the blue line.

Adjacent Non-supplementary Angles

 

The image above is the side of a mirror which people use to look at themselves in. I found it in my dining room. The part of the mirror in the picture has three different pieces. Each piece is positioned at different angle. The angles at which they meet form adjacent non-supplementary angles. These angles are highlighted in blue and green. Another pair of adjacent non-supplementary angles are at the corner of the mirror where two of the pieces of the mirror meet. They are highlighted in orange and yellow and add up to be 90 degrees.

Non-Congruent Alternate Interior Angles On A Seesaw

The object above is a seesaw. Children play on seesaws to amuse themselves. The board on the seesaw where the children (and apple) sit, creates a line. This line is highlighted in dark purple. The ground creates another line which is highlighted in pink. The part of the seesaw holding the board up is highlighted in blue and is a transversal between the purple and pink lines. These three lines create a pair of non-congruent alternating interior angles. These angles are highlighted in yellow. The picture was found on the website:

Skew Lines On A Dining Room Table

The picture above that I took, is of a dining room table in my house's dining room. A dining room table is used by all people to eat on. They can also be used to set things down on or do work on. The highlighted lines on the dining room table are skew lines. Skew lines are will never intersect and are not on the same plane.
