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 sequence of transformations that produces an image not congruent to the original figure typically involves a dilation combined with one or more rigid transformations (such as translation, rotation, or reflection). Dilation changes the size of the figure without altering its shape, resulting in a similar but not congruent figure. For example, if you dilate a triangle by a factor greater than 1 and then translate it, the resulting triangle will not be congruent to the original.
A similar figure has the same interior angles as a congruent figure but its sides are in proportion to a congruent figure.
Yes, two circles remain congruent after reflection. Congruence in geometry means that two figures have the same size and shape, and reflecting a circle does not change its size or shape. Therefore, regardless of the position or orientation after reflection, the two circles are still congruent.
