Although there were earlier instruments that were used for angle measurement in addition to other mathematical. Practice drawing different angles to get more comfortable using a protractor. The protractors in the mathematics collections of the National Museum of American History (NMAH) illustrate stories of technical work and innovation in navigation, surveying, engineering, and war. With this method, you can draw any type of angle you need. That’s it! You’ve used a protractor to draw an angle. If it’s not, you can adjust your second line. Check the angle to ensure it’s 60 degrees. Print our downloadable turntable protractor to get started. Let’s take a look at how to adjust the overhang alignment geometry using a two-point protractor, which is a universal model. This will complete an equilateral triangle. Extend the new lines to intersect the first line you drew. At the end of the line segment, use a protractor to form 30° angles on either side of the line segment. On that line segment, measure off the given line length. Place your protractor back onto the angle with the center on the vertex (where the two lines meet) and the baseline along the 0-degree line of the protractor. Regardless of the one that you use, the process for each is basically done the same way. First draw any line, then draw a line segment perpendicular to the first line. This line will form a 60-degree angle with your first line. Now, using your ruler, draw a straight line from the end of the first line (the point where you placed the center of the protractor) to the mark you made for the 60 degrees. Drag the protractor to appropriate position. Find the 60 on the edge of the protractor and make a small mark on the paper at this point. (Updated: 8 Sept 2016) Measure the angle using the protractor. Let’s say you want to draw a 60-degree angle. Step 3: Mark the Desired Angleĭecide what angle you want to draw. A protractor is a device used in drafting and drawing: its mainly used for drawing and measuring angles. This is 'Year 5 - Week 10 - Lesson 1 - Measure with a protractor' by White Rose Maths on Vimeo, the home for high quality videos and the. Make sure the straight edge of the protractor is aligned with your line. Place the protractor on the paper so the midpoint of its straight edge (the hole marked usually at 0 and 180 degrees) is exactly at the end of the line you drew. Using a ruler, draw a straight line on a piece of paper. Here’s a step-by-step guide to using a protractor to draw angles: Step 1: Draw the Base Line + Ratio, Proportion & Percentages PuzzlesĪ Step-by-step Guide to Using a Protractor to Draw Angles.
