Explain triangle congruence in terms of rigid motions. use the terms corresponding sides and corresponding angles in your explanation

The triangle congruence refers to two triangles that have had a rigid motion as translation, rotation, reflection or the combination between them so both triangles have the same form and its corresponding sides and angles have the same dimension.

Step-by-step explanation:

We say two figures are congruent when they have the same form and dimensions, this mean that we have two equal figures in this case triangles, but they can be in different positions, thats' when we talk about the rigid motions such as translation (when the figure is moved), rotation (when we turn the figure over a center of rotation) or reflected (when we flip a figure over a line or a point), we can also have a combination of this movements but the triangles are not going to change their form or their dimensions, so the corresponding angles and sides, are going to be always the same.
