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.
The Lines and Angles of the World

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.
