1)
The property not preserved under line reflection is orientation.
Option g
(Note: Dilation, rotation and translation are preserved under line reflection).
2)
A congruence transformation is also known as isometry or rigid transformation.
Option e.
3)
A --- invloves three reflections
4)
Since reflection does not preserve orientation, the reflection of quadrilateral does not preserve orientaion
Option g.
5)
The equaivalent of three reflections in parallel lines is a reflection
Option l
6)
In reflection, the figure is flipped over a line.
Option o
7)
A figure with rotational symmetry can be mapped onto itself by a rotation of 180 degree or less.
Option j.
8) Transformation that change the position of a figure without changing its shape and size is known as translation.
Option m
9)
Moving a figure to the right or left and up or down without flipping is
translation.
Option m
10)
In translation, a point, line or image is slided to a new position without any change in shape or size without any flipping.
Option m
