Determine what type of angle you're measuring. A right angle is exactly 90 degrees. If an angle is less than 90 degrees, it's an acute angle. Obtuse angles, on the other hand, are more than 90 degrees but fewer than 180.[2] X Research source In some diagrams, you may see more than one angle. The arc around the vertex shows you which angle you're supposed to find the value of. Labeling an ...Place the center of your protractor on the vertex of the angle. At the bottom of your protractor, you'll see a little hole in the center. Typically this hole has vertical and horizontal lines crossing it, so you can line up the protractor exactly.[3] X Research source To make sure you're right on the vertex, it can help to make a little dot inside the center of your protractor. Then remove ...Line up one line with the protractor's baseline. The baseline of your protractor is the solid line on the bottom with a "0" at either end. Once you have the protractor on the vertex of the angle, adjust either the protractor itself or your paper until one line is following the baseline.[4] X Research source If one line is more horizontal, it will typically be the easiest one to line up along ...Find the degrees in the angle using the correct scale. Along the outside of the protractor are 2 arcs of numbers. Use the outer arc if the angle you're measuring opens to the left. Use the inner arc if the angle you're measuring opens to the right. The number that the other line of the angle crosses is the number of degrees in that angle.[6] X Research source Protractors usually provide ...The protractor is easier to use if you always line up one of the lines of the angle along the baseline of the protractor. Otherwise, you'll have to do more calculations to determine the degrees in the angle. Thanks Helpful 0 Not Helpful 0- 74.3K
The 180-degree angle is a straight angle and forms a straight line. It is exactly half of the full angle (360-degree angle). Learn about the 180-degree angle, its construction, properties in this article.
A 180 degree angle is the measurement of an angle when the sides are on opposite sides of the vertex, and on form a straight line. A straight angle’s vertex angle is 180° in measure. Here, ∠ AOB = 180°.
3 days ago · Textbook Solutions. CBSE Notes. What is an Angle? An angle can be defined as the combination of two rays with a common endpoint. The symbol for an angle is ∠. The corner point of an angle is known as the vertex of an angle. The two straight sides of the angle are known as the arms of the angle.
A standard protractor can measure up to a 180 degree angle. To measure an angle over 180 degrees, you can measure the angle in smaller parts, and then subtract the total from 360 degrees.
Step 1: Draw ray OA. Align the center of the protractor with the point O. O will be the vertex of the angle. Step 2: Mark the 180 degree reading (on inner calibration) as point B. Step 3: Join OB. ∠AOB = 180 o. Constructing 180 Degree Angle Using Compass. Here are the steps to assist you in drawing 180 degree angle using a compass:
