Important Questions on Transformation & Symmetry in Geometrical Shapes
Reflection is a rigid transformation. Why? Write with reason.
On one side of the road an electric pole E, is fixed. The distance of the road from the pole is . Taking the road as the line of reflection, reflect the pole. After reflection what would the perpendicular distance of the image of the electric pole (E’), formed on the other side of the road be from the road?
