Triangles are congruent when all three sides and all three angles of one triangle are equal to the corresponding sides and angles of another triangle. The side-side-side (SSS) theorem helps to determine whether two triangles are congruent. The angle-side-angle (ASA) theorem is also used to find out if two triangles are congruent.

SSS Theorem: The SSS theorem states that if three sides of one triangle are equal to three sides of another triangle, then these two triangles are congruent. ASA Theorem: The ASA theorem states that if two angles and a side of a triangle are equal to two angles and a side of another triangle, then the two triangles are congruent. Congruent Triangles: Two triangles are congruent when all three sides and all three angles of one triangle are equal to the corresponding sides and angles of another triangle.

In Euclidean geometry, two triangles are said to be similar if their corresponding angles are equal and ratios of their corresponding sides are equal. Any triangle can be reflected, rotated, or translated into any other triangle depending on the congruency. Congruency is not only limited to Euclidean geometry. It can be used in spherical geometry as well.
