Geometry Lesson learned!: length and angles of quadrilaterals

All the houses you see, the house you live in, your windows,  the tallest building in this world, your favorite department stores, and even your remote controller or mobile phones were built using Geometry. Geometry is an extremely important subject as it teaches you all about angles and lines of shapes and everything related to shapes. Architects have to be good at Geometry and it's an extremely important topic even if you aren't becoming an architect. When manufacturing something like a can or a guitar, you need geometry. That's how important Geometry is. Our Geometry teacher is Mr.Eubin who is an excellent teacher because he can teach and be funny at the same time (well all teachers in Wells are funny and teach well). So you can say almost everything in this world, like your keyboard and computer, was made using Geometry.

In Mr.Eubin's awesome Math class, we learned how to measure the angles of quadrilaterals, which are shapes with 4 sides. We used Mr.Eubin's equation and used common sense. If a parallelogram had two congruent angles for example, 5x+7 and the other 6x+8, what would each angle be. So we add the two numbers together, making it 11x + 15. Then we equate it to 180, making it 11x = 165. Then you divide 165 by 11, giving us 15. Insert 15 into the equations 5 (15) + 7, and 6 (15) + 8. The first one gives us 82 and the other, 98. That's how you find the length (remember a quadrilateral total of 360 degrees in angles).

I don't have my own picture but this should give an idea.
