📚 Quick Study Guide

    📏
  • Translation: A transformation that slides a figure along a straight line. Every point of the figure moves the same distance in the same direction.
  • 🔄
  • Rotation: A transformation that turns a figure about a fixed point (the center of rotation). Defined by the angle of rotation and the direction (clockwise or counterclockwise).
  • зеркало
  • Reflection: A transformation that flips a figure over a line (the line of reflection), creating a mirror image.
  • ⚖️
  • Dilation: A transformation that enlarges or reduces a figure by a scale factor. The center of dilation is the fixed point from which the figure is enlarged or reduced.
  • Congruence: Transformations like translation, rotation, and reflection preserve size and shape, resulting in congruent figures.
  • ✖️
  • Similarity: Dilation changes the size but preserves the shape, resulting in similar figures.
  • 📐
  • Scale Factor (k): In dilation, if $k > 1$, the image is an enlargement. If $0 < k < 1$, the image is a reduction. If $k = 1$, the figure remains unchanged.
