Congruent, Acute, or Obtuse Angles

Congruent, Acute, or Obtuse Angles

   

      These images show a set of desks and chairs in a computer lab. The pictures relate to the geometric idea of Congruent and Obtuse Angles firstly because they create two angles on each side. Secondly, they form two wide angles shown in the picture below. Lastly, they are both two angle that are also both wide - so therefore they are congruent. This picture was created by myself, I took the picture with my phone. The images in this image can be found in the Mac Lab on the second floor of Creeden at Severn School. In the real world the Mac Lab and the objects within it are used for learning and internet browsing by Severn students. These objects are considered useful in the industry of technology and information.

The image showed above is of a man standing on the beach at sunset. This picture properly displays the geometric idea of a line perpendicular to a plane because the beach or ground is a plane, and the man is like a line, perpendicular to the plane of the beach. This image was found on the internet, but if you can stand on ground you too can display this geometric idea. In the real world the image can be found if you stand on ground which would represent a plane, and you standing on the plane would act like a line. 

Coplanar Parrallel Lines

Coplanar Parallel Lines  

The image above shows a brick wall. It demonstrates the geometric idea of Coplanar Parallel Lines. The picture below shows more clearly the idea stated. A brick wall can be found in the most common of places. Places such as outside, on the exterior of a building, indoors, providing supportive yet stylish walls. This picture was found online - but one may find a brick wall by walking around in their surroundings. In the real world a brick wall is used as a wall in buildings or as a sort of short fence.
