This picture shows non-congruent alternate interior angles. The purple angles show two interior angles. The angles aren't congruent because the do not have the same length. They are alternate because they are on opposite sides of the transversal. They are interior because they are on the insides of the transversal. I took this picture myself with pencils I found in my house. Pencils are an everyday object that students, teachers, doctors, etc. use as a writing utensil.

Supplementary angles that are not a linear pair
Vertical angles
The legs of the piano stand intersect and form two pairs of vertical angles. Vertical angles are formed when two lines intersect. Each opposite pair are called vertical angles and they are congruent. The single red curved lines show a set of vertical angles and the double yellow curved lines show another set of vertical angles. When collapsing the keyboard stand, the angles stay congruent because vertical angles always stay congruent no matter the height. I took this photo of the keyboard in my basement and the legs are used to hold up a piano. Piano falls under the category of music industry.

Angle bisector
This picture of noodles forms an angle with an angle bisector. The purple lines show the acute angle and the green line shows the angle bisector. The middle noodle is an angle bisector because it divides the space between the other two noodles or the angle into two equal parts. The noodles can be found at a grocery store of any kind but I just used ones within my house. They are used for eating. I took this picutre myself and noodles fall under the category of food.
