What is a congruent image in math?

What does congruence mean in math?
congruence, in mathematics, a term employed in several senses, each connoting harmonious relation, agreement, or correspondence. Thus two triangles are congruent if two sides and their included angle in the one are equal to two sides and their included angle in the other.
What is a real life example of congruence?

How do you explain congruence?
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
What is SSS congruence?
When two triangles are congruent, all three pairs of corresponding sides are congruent and all three pairs of corresponding angles are congruent. If all three pairs of corresponding sides are congruent, the triangles are congruent. This congruence shortcut is known as side-side-side (SSS).
What is SSA in math?
The acronym SSA (side-side-angle) refers to the criterion of congruence of two triangles: if two sides and an angle not include between them are respectively equal to two sides and an angle of the other then the two triangles are equal.
Why is congruence important in math?
Congruence is an important mathematical idea for humans to understand the structure of their environment. Congruence is embedded in young children’s everyday experiences that allow them to develop intuitive senses of this geometric relationship.
What is congruence discrete math?
Congruence Relation. Definition. If a and b are integers and m is a positive integer, then a is congruent to b modulo m iff m|(a − b). The notation a ≡ b( mod m) says that a is congruent to b modulo m. We say that a ≡ b( mod m) is a congruence and that m is its modulus.
