Before getting to learn about angles I think it’s just an easy topic for kids to learn. I also think that only measuring the angle is adding to the topic but it’s just thinking. In reality, all the math topic is hard. Read this until the end if you want to know about **Angle**.

Round 4 is nothing much different from other round but just different topic of math. Angle is also one a topic in math. For this round, I have learned about how to measure the angle in the weird shape and plus the angle. Also, I learned some word which is related to angle, but I did learn a lot of them from last year already, somehow I think it’s just a review from this round. Acute is an angle that is lower than 90 degree and Obtuse is an angle that is higher than 90 degree but lower than 180 degree, the equilateral triangle is a triangle that has their three shapes equal to each other and the isosceles triangle is a triangle that has two same shapes and one other different shape. In the other hand, all of our students should know that in a triangle there should be 180 degrees. Besides that, I understand how to solve the problem of angle with less clue and in 2+ shape combine together.

**Obtuse angle**

I encourage you all to learn math harder because all the lessons in math are harder than you think and most of the thing in life is using math to solve a problem. In my opinion, math is the most important topic to learn, in real life math have been used everywhere.
