Mathematics can be said to be everywhere in our lives. When we pay for things in the supermarket, when we measure the area of a thing, when we make objects with various shapes such as parallelogram, right angle and triangle, we can directly use mathematical knowledge in our lives. A few days ago, something happened in our family to solve life problems with mathematical knowledge.

When I came home from school that day, I sat in a small chair and heard a "crunch", which scared me to jump. Ha, it turns out that one leg of the chair is loose. "How about we fix the chair?" I said to my parents on impulse. Mom and dad said "yes" with great support. So the whole family began to get busy, looking for tools, holding chairs and nailing. After the "scratching" sound, several big nails were nailed into the loose chair legs. "Hey, it's finally nailed." I clapped my hands and sat up with satisfaction. Crunch. Hey, what's up? What should I do? Suddenly, I remembered what the math teacher said: triangles can stabilize objects. Yeah, why didn't I think of that just now? I immediately found a small piece of wood, cut it into four small triangular pieces of wood with the same size according to the angle formed by the four legs of the small chair and the chair surface, and then filled the triangular pieces of wood in the gaps between the chair legs and the chair surface respectively, and nailed them firmly. Needless to say, this chair is safe to sit on.

Hey, these numbers are amazing. It seems that I must study mathematics harder in the future, apply mathematics to every bit of life, analyze and solve practical problems in life, and better adapt to the development and needs of society. Make life more meaningful.
