# how to measure an angle with a protractor

Now, we use the following steps for required construction . Measuring Angles with a Protractor. Line up one side of the angle with the zero line of the protractor (where you see the number 0). ‎Protractor helps you to measure angles quickly and easily. When measuring angles using a protractor it is important that the reading always begins at zero. Edit. 4th - 12th grade . Save. By using a protractor or by employing trigonometric methods, determine the angle of inclination for the ramp Having finished the set-up, use a stopwatch to measure the time it takes for the marble to roll 70cm down the ramp. The main problem with this protractor is that the 'origin' swivel point can't be accurately placed over the object you are trying to measure because you can't see where it is. This is how you can use a protractor to measure as well as draw angles, quickly and easily. Draw ∠BXA = 110° with the help of a protractor. Easy measure angles, using interactive whiteboard angle simulator. Using a protractor, accurately sketch an angle with a given angle measurement. Measuring angles accurately In this video you will learn how to use a protractor to measure angles accurately. And that is the right answer. Step4. You have the possibility to set the interval of the angles; if the starting angle is 0, 180 or random. Measure angles using a circular protractor to avoid the mental trap of shapes of angles. A compass helps to construct an angle.. Set squares, also known as triangle protractor, are used to draw parallel and perpendicular lines.
