How to Construct 80 degrees using a protractor. ∠ABC = 110 degrees is the required angle.
Mark point A next to the 110 degrees mark on the scale. We consider the scale which has 0 degrees near point C for construction. How to Construct 110 degrees using a protractor. Mark point A next to the 75 degrees mark on the scale. How to Construct 75 degrees using a protractor. Mark point A next to the 90 degrees mark on the scale. Place the protractor with its point O on the point B of the line segment BC. How to Construct 90 degrees using a protractor.ĭraw a line segment BC, which is one of the arms of the angle that is to be constructed. Construction of Angles Using a Protractor Examples Make use of our page and score the highest marks in the exams. Students can find the worksheets, practice tests for all the subjects. Make math your favorite subject by practicing the problems given in 5th grade math. Math is the easiest and interesting of all the subjects. We consider the scale which has 0 degrees near the point for construction. Place a protractor with its point on the point of the given line segment.ģ. Draw a line segment, which is one of the arms that is to be constructed.Ģ. Let us see some steps on the construction of angles using a protractor from here.ġ. In order to construct or measure the angles may be acute, obtuse, or right angle we need a protractor. One set is from 0 to 180 degrees and the other set is from 180 to 0 degrees. There are two ways to measure the angles.
The construction of angles plays an important role in geometry. That common point is known as the vertex of the angle and the two rays that form the angle are called its arms.ĭepending upon the inclination between the two arms an angle may be acute (less than 90 degrees), obtuse (greater than 90 degrees), right angle (equal to 90 degrees). An angle is made up of two rays that start from a common point. Before we talk about the construction of an angle using a protractor, let us recall the angles and the types of angles. Protractor is an important instrument in geometry.
