Answer with explanation:
⇒When a design or geometrical shape is reflected over Axis, which is lying in two Dimensional plane,the two, Pre-image that is geometrical shape before reflection and geometrical shape called Image after reflection , they both are congruent to each other.The Line through which the two,Image and Pre Image , are congruent in the plane, is called "Line of Reflection".
⇒When Reflection through a line takes place, corresponding Sides of two designs are congruent,means equal, and the Corresponding interior Angles of two designs are also Congruent.
Option C:⇒ Congruency
