Examples recognizing transformations
Khan Academy・2 minutes read
The video discusses various types of transformations: rotations, translations, reflections, and dilations, each with specific characteristics and effects on figures. Triangle A was translated into triangle B by shifting all points to the right and up, while quadrilateral A was dilated into quadrilateral B, with different sizes and increased distances between corresponding points. The center of dilation was located just outside trapezoid A.
Insights
- Understanding transformations in geometry involves recognizing rotations, translations, reflections, and dilations, each with distinct characteristics like spinning, shifting, flipping, or resizing figures.
- The specific examples of triangle A transformed into triangle B through translation and quadrilateral A into quadrilateral B through dilation highlight how these transformations alter shapes by shifting points or changing sizes, emphasizing the fundamental changes that occur in geometric figures.

Types of Transformations: Rotations, Translations, Reflections, Dilations
- Different types of transformations are discussed in the video: rotations involve spinning around a point, translations shift all points of a figure, reflections flip a figure over a line, and dilations either shrink or expand a figure.
- Triangle A was transformed into triangle B through a translation, where all points were shifted to the right and up, indicating a clear translation.
- Quadrilateral A was transformed into quadrilateral B through a dilation, as the figures are different sizes and the corresponding points have increased distances, with the center of dilation just outside trapezoid A.
