The shape A is congruent to shape B as the size and shape are the same.
What is congruency in geometry?
In geometry, congruency refers to the property of having the same size and shape. Two geometric figures are said to be congruent if one can be superimposed onto the other after a series of rigid transformations, such as translations, rotations, and reflections. When two figures are congruent, it means that their corresponding sides and angles are equal in measure.
This occurs with the shapes given as they have exactly the same size, the same angles, and the same shape, which means they can be superimposed and will match perfectly.
