Question

  1. identify the transformation between the two triangles:○ translation○ reflection○ rotation○ none of these2. identify the transformation between the two arrows:○ translation○ reflection○ rotation○ none of these3. identify the transformation between the two shapes:○ translation○ reflection○ rotation○ none of these4. identify the transformation between the two shapes:○ translation○ reflection○ rotation○ none of these

Explanation:

Brief Explanations
  1. 第一组图形:两个三角形仅大小不同,平移、反射、旋转都无法改变图形大小,所以不属于这三种变换。
  2. 第二组图形:两个箭头呈镜像对称,符合反射(轴对称)的特征。
  3. 第三组图形:右侧箭头可通过左侧箭头绕某点旋转得到,符合旋转的特征。
  4. 第四组图形:右侧图形可通过左侧图形绕某点旋转得到,符合旋转的特征。

Answer:

  1. None of these
  2. Reflection
  3. Rotation
  4. Rotation
