No its not
Yes
Yes, due to the definition of congruent figures.
translation
A translation, a reflection and a rotation
only if the mirror is flat
Figures are congruent if and only if they are related by a translation, reflection, or rotation, or some combination of these transformations.
It will be as you term it 'horizontal stretch' in which the figure is enlarged or reduced in size.
No, a figure and its reflection image are congruent. It is like our reflections in a mirror. Hope I answered your question!
Two transformations that can be used to show that two figures are congruent are rotation and reflection. A rotation involves turning a figure around a fixed point, while a reflection flips it over a line, creating a mirror image. If one figure can be transformed into another through a combination of these transformations without altering its size or shape, the two figures are congruent. Additionally, translation (sliding the figure without rotation or reflection) can also be used alongside these transformations.
A similar figure has the same interior angles as a congruent figure but its sides are in proportion to a congruent figure.
The reflection in a line will be another congruent circle.
When u rotated a figure 180 is the reflection the same
