Final answer:
The statement regarding finding centers for standard bend angles on a new mechanical or electric bender for accurate bending is true.
Step-by-step explanation:
The statement that centers of the various standard bend angles must be found, and the shoes marked on a new mechanical or electric bender in order to use the push-through method of bending is true. It is essential to mark the bend centers accurately to achieve precise bends when using a mechanical or electric bender. Failure to mark the bend centers correctly can lead to inaccurate bends and waste of materials. This step is critical in ensuring that the bends made in pipes or conduits meet the required specifications for various applications.
