Non-Congruent Alternate Interior Angles

The chopsticks above perfectly represent non-congruent alternate interior angles. I found them in my kitchen. Chopsticks are a important utensil used in the food industry, especially in Asian restaurants. The angles are formed by two lines and a transversal and lie outside the two lines and on opposite sides of the transversal, the angles measures also are not the same

Congruent Acute Angles

In the picture above, the orange straws show congruent acute angles. The pink lines highlight the angles. Congruent acute angles are angles that have the same measures that equal less than ninety degrees. Straws are used in the food industry because restaurants hand them out to people who order soft drinks and sodas

Line Perpendicular to a Plane

On the bookcase above, which is located in my home office, I was able to spot a line perpendicular to a plane. The pink lines represent the plan, or the framing/backboard of the bookcase. The blue lines highlights the line, in this case the shelf, that is perpendicular to a plane. The green box shows that the line is perpendicular to the plane because when line are perpendicular, they form a right angle. Bookcases, or shelves, are used in the food industry to hold dishes and cookware, they can also hold cookbooks

Supplementary Angles that are not a Linear Pair

The pink lines above highlight supplementary angles that are not a linear pair.  The angles were found on the Leaning Tower of Pisa, locate in Pisa, Italy. The Supplementary angles equal one hundred eighty degrees, and are adjacent because they are next to each other.

Adjacent Non-Supplementary Angles

The are many adjacent non supplementary angles located on the building above. The green lines highlight the adjacent non supplementary angles. The building is the hearts building located in new york city. Adjacent non supplementary angles are angles that are next to each other, and don't equal one hundred eighty degrees.

Skew Lines

The pink lines highlighted on the skillets above represent skew lines. Skew lines are lines that are not parallel and do not intersect. Skillets and other cooking pans are used very often in the cooking industry to prepare dishes. I found the pans in my kitchen.

3 or More Coplanar Parallel Lines

A common tool used in the food industry is a grill pan. Restaurants use them for indoor grilling when they can not grill outside. The pan is a plane, and within the plane there are many parallel lines, represented by the raise bars that create grill marks on steaks and burgers. The yellow lines highlight 3 coplanar parallel lines-three parallel lines that lie on the same plane. The pan can be found in many homes around the world, that is were i found mine. The picture was taken by myself.

Segment Bisector

I found a segment bisector on the tennis court pictured above. I'm not exactly sure where the photo was taken. The pink line represents the segment. The yellow line represents the segment bisector. If you look close fully at all different kinds of sports courts, you can almost always see a segment bisector

Monumental Angles

If you look close fully at the eiffel tower, the most iconic land mark in Paris, you will be able to spot vertical angles. The mint green lines represent one vertical angle, but their are hundreds more located within the massive iron structure. The braces, in the cases the vertical angles, support the structure. Many of these x shaped, vertical angle-esque braces are used in the construction industry to support tall structures.

Angles at Paris Fashion Week

In the picture above I found a angle bisector, which is a ray that divides an angle into two angles that are congruent. The photo was taken at S/S13 fashion week in Paris. The angle bisector is located within the structure and stitching of the timeless navy blue Dior handbag. The red line represents the right angle found on the bag, and the green ray is the angle bisector, which was stitched into the bag to create the brands iconic quilting. Many people carry structured handbags around the world, and if you look close enough, you will notice the different types of angles within.
