- For the blue triangle, rotate 90° anticlockwise about the marked point: the horizontal base becomes vertical and points upward, the vertical side becomes horizontal and points left, maintaining the right angle at the pivot.
- For the yellow rectangle, rotate 90° clockwise about the marked point (bottom-right corner): the bottom edge becomes vertical and points down, the right edge becomes horizontal and points right, so the rectangle now extends downward and to the right from the pivot.
- For the green triangle, rotate 180° about the marked point (near its base): each vertex moves to the opposite side of the pivot at the same distance, flipping the triangle upside-down and mirroring its orientation horizontally.
Parent Tip: Review the logic above to help your child master the concept of rotation worksheet.
