Verified Answer :

Answer:

Correct option is C

Step-by-step explanation:

we have to tell that in which type of transformation angle are preserved.

Rotation:

This transformation turns a figure about a fixed point and the fixed point is known as the centre of rotation. The figures which goes through rotation has same angle as that of original figure.

i.e Rotation transformation preserves angle.

Reflections:

This transformation flip a shape over a line.

Angles also preserve in this type of transformation.

Translations:

This transformation involves sliding a shape. The figure only translate right left i.e shape or angle preserve i.e not changed.

Hence, the angles are preserve in in all three type of transformations that are rotation, reflection and transformation.

∴ Correct option is C
