What Are Three Tools Used to Measure Angles?
In addition to standard dimensions in length, the angle is one of the most common home construction calculations. Framing, roofing and basic woodworking all depend on exact angle measurements and cuts. Without specialized tools, even simple angles can be impossible to measure. This article covers three tools professionals and homeowners use to measure angles. Consider adding one or all of these tools to your workshop before tackling another remodeling or construction project. Does this Spark an idea?

Benefits
-
Use the proper angle measuring tool for the job Most avoidable structural issues in home construction and renovation stem from poorly fitting joinery and framing that is out of square. Those costly mistakes result from careless measuring errors and use of improper tools. Standard linear measuring tools, such as tape measures, were simply not intended to measure angles. Purchase specially designed angle measurement tools to ensure precise woodworking joints and perfectly plumb walls.
Hand Squares
-
Hand squares can be used to measure virtually any angle for any construction application.
A framing square makes it possible to easily measure true right angles when building stairs, rafters or wall framing. A framing square is an L-shaped measuring tool marked with various measurement increments.
A combination square feature a head that slides along a ruled metal blade. This square is typically used to measure both 45 and 90-degree angles.
The carpenter's square is actually a metal triangle. One side of the triangle is marked in inches and the second side features raised edges that allow the tool to be placed securely against the work piece. The third, longer side is marked in degrees from zero to 90 to assist with miter cuts.

Protractor
-
The common protractor is a semicircle with degree marks on the outer edge from zero to 180 degrees. These degree increments radiate out from the center base of the protractor. The carpenter or builder's protractor is made of steel or aluminum for longer life and durability.
Carpenters now use digital or dial protractors that measure up to 360 degrees. Those protractors consist of two flat metal bars attached by a hinge at the location of the digital readout or dial.
Angle Divisor
-
The angle divisor is a versatile measuring tool to determine internal and external angles. This tool is constructed of heavy aluminum and features an adjustable, four-sided shape that glides along a center ruler. Simply create the desired angle or push the divisor into an existing corner and tighten the locking screw. The angle measurement can be transferred and used in for construction application. The angle divisor combines the features of a sliding T-bevel, miter square, combination square and protractor.
Considerations
-
When purchasing a tool to measure angles, first match the tool to your particular measuring task. Budget is also an important consideration. Shop for the best price. To save money, look for a single tool that performs multiple types of angle measurements. If the measuring tool will be used on job sites, consider durable materials and construction. Compare warranties for measuring tools with moving parts and electronic components. Take into account personal preferences based on tool weight, size and ease of operation.
