It will be as you term it 'horizontal stretch' in which the figure is enlarged or reduced in size.
Figures are congruent if and only if they are related by a translation, reflection, or rotation, or some combination of these transformations.
transformation
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.
It is a rotation.
Segments are congruent when they have the same length. This means that if you measure two segments and find they are equal in measurement, they are considered congruent. Additionally, congruence can be established through geometric transformations, such as translation, rotation, or reflection, which can show that one segment can be mapped onto another.

A glide reflection is where you reflect the shape and translate it. A glide rotation is where you rotate a shape and translate it. A glide translation doesn't exist.
