Composite Solid

This is a picture of a water bottle. This water bottle is a Composite Solid with its large cylinder body and smaller cylinder connected cap.  This object was found in Mr. Klein's classroom and can be seen or purchased elsewhere in stores. The item is used to contain liquids. 

Trapezoids

     This is a picture of a YWCA building.  The image shows two Trapezoids, a green one and a red one.  The green one is an awning, which are typically used for shade or rain cover and can be found on the otuside of buildings or shop entrances.  The red trapezoid is the YWCA logo and is usually shown on all their facility buildings. 

A Regular Hexagon

This image shows a silver nut connected to a bolt.  The shape of this nut represents a regular hexagon.  It can be determined as a regular hexagon because it has 6 different angles and lines connecting. I found this nut connected to a bolt in my garage, however, they can also be found in Home Depot or other construction stores.  Nuts are used in many mechanical structures such as washers, stoves, machines, and many more.  Nuts are also commonly associated with bolts. 

Non-congruent alternate interior angles

       This image shows 2 black pens parallel to eachother and a yellow highlighter bisecting the two.  The image gives an example of non-congruent alternate interior angles.  The two alternate interior angles cannot be congruent in this example because they are both congruent to their vertical angles.  The objects in this picture are used for writing or drawing and were found in my pencil case.   

Line Perpendicular To A Plane

When a line is perpendicular to a plane it forms multiple right angles and stands directly away from the plane.  In this picture the frame resting on top of the desk represents the perpendicular line meeting the plane.  Both of these objects, the desk and frame, are located in my room.  The desk can be used as a study space or to hold things within it; the frame can be used to hold pictures. 

Skew Lines

 This object is a rectangular shaped, wooden drawer and has skew lines defining it.  Wooden drawers can be found in dressers or desks.  Skew Lines, however, can be found in windows, blocks, boxes, houses, and in many other objects.  Skew Lines are two lines that do no intersect and are not parallel or coplanar.  Even though Skew Lines aren't necessarily used for many things, they are found in almost everything.  

Congruent Isosceles Triangles Are Everywhere!

This is a picture of a bed frame.  The design of the metal frame forms an Isosceles triangles.  An  Isosceles Triangle has at least two congruent sides.  As you can tell, this object forms a triangle and has two congruent sides forming up to the apex of the triangle.  An Isosceles Triangle can be an acute, obtuse, equiangular, and even a right triangle! In this picture, the triangle is either an acute or equiangular isosceles triangle.  An Isosceles triangle is seen in everyday life in things such as: pizza slices, bicycle wheels, architectural structures, all the way to kaleidoscopes or even light rays!
