The new semester has started and everyone has learned new knowledge. Me too. It's been a few weeks since school started, and we have finished the first two units. I learned a lot of new knowledge in the first two units. The first unit learned the transformation of graphics. The second unit is about factors, multiples, prime numbers and composite numbers.
The first unit learned the drawing method of translation, rotation and symmetrical figures, and learned that the corresponding points of symmetrical figures are equal in distance from the axis of symmetry. Lines connecting corresponding points are perpendicular to the axis of symmetry. A simple figure can get many beautiful figures by rotating. In real life, we often use rotating graphics.
Unit 2, I learned that the minimum factor of a number is 1 and the maximum factor is itself. The number of factors of a number is limited. If a number has only two factors: 1 and itself, it is called a prime number. A number is called a composite number if it has other factors besides 1 and itself. 1 is neither prime nor composite.
I have learned so much in the first two units, and I hope I can learn more in the next unit.
