Define “framing square”.

A framing square, also known as a framing or roofing square, is primarily used in carpentry for marking right angles and lengths. Its design typically includes a large, L-shaped metal piece with one leg longer than the other, allowing carpenters to easily create and check 90-degree angles — an essential factor in ensuring that structures are properly aligned and square. This tool also features graduated markings that assist in measuring lengths and layouts, making it particularly useful for framing walls, roofs, and floors.

The distinction made in the choices clarifies that while other tools may assist with measuring distances, cutting materials, or leveling surfaces, the specific functionality of a framing square centers around marking angles and lengths, which supports precise construction practices. Therefore, recognizing the framing square's unique contribution to creating accurate angles and performing layout tasks is key to understanding its role in carpentry.
