Yes, shape was rotated but stayed the same shape and size so they are congruent.
To determine congruence using transformations, we need to check if we can map one triangle onto the other through a sequence of rigid transformations, such as:
Translations: Sliding the triangle without changing its size or orientation.
Rotations: Rotating the triangle around a fixed point by a certain angle.
Reflections: Flipping the triangle across a line.
If we can map one triangle onto the other using only these rigid transformations, then they are congruent. Otherwise, they are not congruent.
