Explore transformations video lessons on rigid transformations including translations, reflections, and rotations, as well as the non-rigid transformation of dilation. Rotate figures 90° clockwise or counterclockwise and 180° about the origin, reflect shapes across the y-axis and other lines of symmetry, and translate figures on the coordinate plane. Learn how scale factor controls dilation, where values greater than 1 enlarge and values less than 1 shrink a figure, using the origin or another point as the center of dilation.
