Vertical Lines

The branches in this picture show vertical angles. <1 and <4 are congruent and <3 and <2 are congruent. Trees are used to make important items in our everyday life such as chairs, desk, beds, ect.

Three or more coplanar lines

These pictures are examples of coplanar parallel lines. You know that the lines that are highlighted are never going to run into each other because they are parallel. In the stop sign, the bridge, and the picture frame you know that the lines are coplanar because they are on the same plane, or in this case on the same object. (In the stop sign the top and bottom of the sign is coplanar. In the frame the two sides/the width are coplanar.) The stop sign is used for cars when they passing, it is used to keep peace and have certain secruity. The bridge is used for cars to pass ontop and for boats to pass under wen the need to get across. The frame is use dto keep memoris whether your with your friends or family. They are used to preserve art.

Segment Bisector

This an example of a Segment Bisector. A segment bisector is a line or a ray or a segment that divides a line segment into two equal parts. Which is shown in this picture.

This  kite that is used as toy for children.

Line Perpendicular to a plane

This represents a line perpendicular ot a plan. I say this because the paper is going through the plane which is the cap. In this there relly isnt a use for the objects used in this picture.

Congruent acute or obtuse angles

This picture is of a regualr building that has a very intresting outside. The outside of the building forms two congruent acute angles. You can tell that they are congruent by the curve in each drawing.

Adjacent non-supplementary angles

In this picture I used a picture of wood crossing which makes a right angle. The right angle would be split. This would make the angle adjacent because they are together and non-supplementry because they don't add up to 180 degrees. Wodd is used to make buildings, to make toys. Wood has a wide range of uses from carpenter to artist.

Angle Bisector

This pizza shows an angle bisector. An angle bisector is something that is divided by a line at the vertex. In this picture the 3 pizza slices shows an agle bisector. Pizza is enjoyed by a lot of people and there are many different combinations and flavors.

Non-Congruent alternate interior angles

In this picture the railroad tracks show non-congruent alternate interior angles. The alternate interior would be <3 and <6 or <4 and <5. Railroads are used tot ransport people adn goods across vas lands. They are very important to society.

Skew lines

This rubix cube is an example a skew line. The lines that are highlighted are not coplanar, parallel, or do not intersect *(The dotted line is supposed to be the other edge of the cube). Rubix Cubes is a toy that is used to test the brain of people of all ages.

Supplementry angles that are not a linear pair

The books in this picture represent supplemnerty angles that aren't a linear pair. Since the books aren't together/ adjacent but still add up to 180, they qualify to be supplementry agles that arent linear pairs. These books are used for EVERYTHING in the modern world, they are used to tell us about history. They can inform,entertain, and persuade.
