Angle Transfers Duplicate or transfer any angle. Multi-Angle Transfers Transfer multiple angles, draw parallel lines, or create a template to make repeated patterns and measurements. Measure angle/altitude of on shore object (tower/lighthouse) to determine distance from your location. Triangle Straightedges/Protractors A protractor and triangle in one, use these tools to quickly set any angle from 0 to 90. Use, string of fishing line tied to the vertex with weight at the other end to determine the angle. Convert the protractor into quadrant to measure the altitude of Polaris to determine latitude at night. On shipboard, string through the hole with weight can be used to determine, long distance course. string fixed through the hole can be used on a chart to determine, long distance course. Some brands also include cutout templates for making circles. Most triangles feature both inch and metric calibrations, an inking edge, and a center cutout. Hole at the vertex of the protractor allows the point of the divider or pencil to be placed on a meridian for a quick accurate course measurement 4. Adjustable protractor triangles allow tracing of angles from 0 to 90, with inner gradations that show the degrees of two different angles. Place protractor vertex over meridian of longitude to determine course or bearing 3. Slide two triangles to transfer course or bearing.

Both pencil and pencil sharpener are included with the Professional Protractor Triangle and this product is backed by our lifetime warranty. Step 3: Place the protractor at the other end of the initial horizontal line and make one of the other two remaining angle measurements given in the problem. It has both 320mm, 1-80,000 scales and is constructed of heavy duty clear 5 mm thick acrylic for durability with handle for ease of use. The Professional Protractor Triangle with handle is larger than other navigation triangles on the market with legs that are 9.312 inches long and a hypotenuse (long side) 13.125 inches long.
