Geometry is an important lesson in math and it can be used for engineering, architecture, graphic design…. In the class, I learn about finding the area and the perimeter of the triangle, square, rectangle, and parallelogram. Through the lesson, I face a lot of challenge because there are many shapes and formulas and especially the triangle. However, my math teacher had given everyone a website call khanacademy(http://khanacademy.org) to work on. It a website where the teacher can put any assignment about any subject for us to do. Moreover, If you don’t understand it you can go to watch some videos where they explain to you about the topic.

Ratio is using math to compare things. For example, if you wanted to compare the number of Female and male in the world you also can use the ratio to do it. In ratio, we use “:” to represent the word “to” like“ 3:4 ” you call it “three to four”.Even though the number is big, you can simplify it in a smaller fraction. Example, if you a have “12:24” you can simplify it in to “1:2” so it makes us easier to compare it.

After all, I learn a lot of things that can apply it to my everyday life or to the future. if I am an engineering in the future, I can use geometry to help me with it.
