# Comprehend the meaning of congruent triangles - Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.

# Properties of Congruent Triangles:<br>
* If two triangles are congruent, then each part of the triangle (side or angle) is congruent to the corresponding part in the other triangle.
i.e. CPCTC, which stands for "Corresponding Parts of Congruent Triangles are Congruent".
* In addition to sides and angles, all other properties of the triangle are the same also, such as area, perimeter, location of centers, circles etc.
