The annual kite-flying competition in Class 4 (1) of Xie Qiao Central Primary School in Changshu was held in our school again. You see: the children on the playground are running and jumping, pulling their kites with all their might, and colorful kites are scrambling to fly high. We spectators are cheering, cheering for the winners and cheering for the losers!

When I got home, I told my mother about the kite-flying competition.

My mother smiled and said to me while listening, "Qin Si, do you know?" Flying kites also has math problems!

""ah!

Thanks for the kite. Is there a math problem? "I asked my mother strangely.

"Then tell me, why do some kites fly high and some fly low in the same environment?" "This must have something to do with the skill of the kite-runner, and of course the length of the kite string." "Well, you're right, skill is on the one hand. But if two students with the same skills have the same kite, will their kites fly as high? " My mother asked me with a smile.

"ah!

This makes me ask. "Yes, the kites used in this competition are all bought by the school, and the size and model are the same. Why do some people fly kites so high? Mom saw that I was stumped, so she handed me a pair of chopsticks instead: "Come on, use chopsticks as kite strings and study them!"! "

"I took chopsticks and compared them on the table. Suddenly, I found that two chopsticks have different angles with the ground and different heights. The greater the included angle, the higher the height from the ground. It seems that if a kite wants to fly high, the angle between the kite line and the ground should be as big as possible. Mom affirmed my statement.

Mathematics is really everywhere in life. Even a humble kite can cause some math problems. It's amazing!
