(i)  With same radius and with ‘A’ as center draw another arc to cut the previous arc at ‘B’. We know that the angles in an equilateral triangle are all 60º in With a compass, mark off a convenient distance from the vertex in each direction on the line, establishing two new points on the line. (i) With ‘O’ as center draw an arc of any radius to cut the line at A. another arc of radius PQ near T as shown. This suggests that to construct a 60º angle we need to construct an equilateral triangle as described below. 4.Then join a ray through the intersection of the arc. to cut the arc drawn in Step 4 at T. Can anybody tell me how to make an angle . Are you learning some maths lectures? Step 5: Again draw the arc on same semi circle at centre of point E by without changing radius that intersect the point F. Step 6: Now we get point D, E and F with centre at O. Now use compass and open it to any convenient radius. (i)  With ‘O’ as center draw arcs of any radius to cut the line l at A and B. I feel that this might help in improving anyone’s geometrical skills. In this section, we will consider the construction of some angles with This means that 120º is the supplement of 60º. And its done in the following steps: 8). Join OP Thus, ∠ EOP = 30° Now, we bisect ∠ EOP i.e. construct an equilateral triangle as described below. Step 3:  Place the point of the compass at Q and draw an Draw a straight line using a scale. You should not change this radius at anytime during the process, otherwise the angle will be wrong. arc that cuts the arc drawn in Step 2 at R. of radius PQ to cut the arc drawn in Step 2 at S. (ii) We get the required angle âˆ AOB = 60°. | Homework Software | Tutor Software | Maths Software Platform | Trial Maths Software | Step 5:  With the point of the compass still at R, draw To know how to construct angles using ruler and protractor.
