Explanation
Transformational proofs use properties of transformations to show congruence or similarity.
Steps:
-
Identify the type of transformation.
-
Apply the transformation to one figure.
-
Use properties to compare the transformed figure to the other.
-
Conclude congruence or similarity.
Example:
-
Prove triangles are congruent using rotation and translation.
-
Prove shapes are similar using dilation.
Why important: Makes proofs visual and easier than classical triangle proofs.
