In this non-linear system, users are free to take whatever path through the material best serves their needs. * Draw a straight line with the ruler, and mark a point on it. To retrieve the measurements from the blueprint, you need to use a specialty ruler referred to as a "scale or architects rule." OK then, to the discussion. Digital ruler-based angle meter. 1) make the angle into a right triangle 2) measure the base (let's call it b) 3) measure the height (let's call it h) 4) the angle is the arctan or inverse tangent of (h/b) More detail please, not sure what you are referring to. A ruler and compass construction refers to constructions using an unmarked ruler and a compass. Here are some points and mental pictures that will help you to understand how angle measurement works. Draw a vertical line connecting the 2 rays of the angle. [1] Architects, engineers and carpenters frequently must measure angles, as for example the angle formed by the ground and a wooden railing on a flight of stairs. The angle between the fence lines is now exactly 90 degrees. It is defined in reference to a right triangle, which is a triangle with a 90-degree angle in it. If your document has an existing measuring line, selecting the Ruler tool causes it to be displayed. You should use a special device for measuring angles - a protractor. It has an additional feature called Chaining Mode that allows one to connect several devices with a Measurekit app in one measuring session and measure floor area in a chain. Move this midpoint to set the vertex of the angle. If this line is the ground, all the easier. We can measure lines using a tool called a ruler. Step 3.
