1. How do you prove congruence through transformations?
konstantin123 [22]

One can prove congruence through transformation if they have the same shape and size.

The congruency postulates include:

  • SSS - Side-Side-Side
  • SAS - Side-Angle-Side
  • ASA- Angle-Side-Angle
  • AAS - Angle-Angle-Side
  • RHS - Right angle-Hypotenuse-Side

<h3>What is congruence?</h3>

In geometry, it should be noted that two figures are congruent if they have the same shape and size.

In this case, if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

One can prove triangle congruence using congruency postulates by using the SSS theorem( side side side theorem).

It should be noted that the congruence postulate is used to illustrate that the triangles are equal.
