Final answer:
The cutting technique where all lengths finish at the same plane is known as a Crosscut, which is different from the other cuts like Miter, Bevel, and Compound cuts.
Step-by-step explanation:
The cut technique where all lengths finish at the same plane is known as a Crosscut. A Crosscut is typically made perpendicular to the grain of the wood and is used when you want to cut a piece of wood to a specific length. The other options listed, such as Miter cut, Bevel cut, and Compound cut, are different in that a Miter cut is made at an angle across the width of the wood, a Bevel cut is angled through the thickness of the wood, and a Compound cut combines both a Miter and Bevel cut. The Crosscut ensures a straight, smooth finish exactly perpendicular to the sides, providing that all lengths finish at the same plane.
